Mufflers and tips

[Reaper948]

As far As i'm gonna go righ now with the exhaust system now,
Id like to change up the Mufflers and MAYBE the tips

No headers yet or H or X pipes....

The shop I installed my HIDs at said that I could put in Flowmaster 50 Series

Yes? No? Maybe so? Anyone have suggestions for tips?

Also can anyone tell me the muffler diameter entry and exit? Thanks (sorry i dont know the correct terminology for that one)

[Butch]

I have the 40s. I like them a LOT better than the 50s. Our last MM meeting for our area gave us a chance to listen to the difference. I *feel* that most everyone agreed that they like the 40s better, if you are after that louder, deep throaty sound.

I feel that the 50s were quite a bit softer in sound, but still sounds very good.

Maybe some of the others that were listening to the differences can give their 2 cents since I may be a little bias being that I already have the 40s.


So....I feel that it depends on how much rumble you want.

[joflewbyu2]

tips are heavy as h#ll, 13 lbs for both. i went with the clean stealth look of the Borla polished turn down tips - same look as a trooper car. the oem pipes and mufflers are also heavy as h#ll.

[Petrograde]

anybody have a part # for the paticular Flowmaster 40's in our MM's?

[Reaper948]

942041

[Stephen Soulsby]

That part number is for 2" inlet/outlet. I thought our piping was 2.25" which would make the part number 942441 (same muffler, just 2.25" inlet/outlet).

[Zack]

Ive seen exhaust shops weld new muffler hangers to the floorboards. Big no no. Exhaust noise is transmitted through metal and can prove to be very annoying. My exhaust shop bent bar stock to fit into the stock hangers and welded them to the mufflers. Make sure it is done properly!!

Actually, you could use either one because the exhaust pipe (inlet) is 2" and the tail pipe (outlet) is 2 1/4". Either way, you'll have to adapt, and it's probably easier to stretch up than it is to neck down. You're going to need a muffler that has a centered inlet, and an offset (towards the outside of the car) outlet. No matter which muffler you install, you'll be adding a section of pipe somewhere because none of the aftermarket mufflers match the length of the OEM muffler.

Y'all should consider the Ravin Z-55 series too, great sound with or without Wes Chain tips. There's a sound file of a Mustang 4.6L at their web site, www.goravin.com Check it out, and save yourself some coins to boot. Two Z-55 mufflers with install and added pipe and hangers is under 300 bucks around here, check that against the cost of the popular brand names, eh?

[sprtyworty]

You're right Serge. Love the Ravins just a nice throaty sound and they are quite when not under acceleration or decelleration(spelling?)

[Reaper948]

Ill check it out.....
Whats the part number for the Ravin mufflers?
Is it RA554242?

[Straightpipes]

Get glass packs all other mufflers don't sound really that much louder. Trust me I experimented with flowmasters and many others. It is due to the 4 cats that cat has. Mufflers don't do the trick. If you want a muscle car sound you need at least glass packs if not straight pipes.

[Reaper948]

Loud is an issue, but quality is also an issue.
I live in Suburbia, so when my Exhaust starts popping and cracking when I let off the gas, that could be an issue. Although it's not really my preference to have solely volume.

[Reaper948]

Sarge, I went and heard the Ravin's and then I heard the flowmasters,
I really would like a rumble even when the car is in idle,

and according to sprtyworty, the Ravins just dont seem to have that....
You're right Serge. Love the Ravins just a nice throaty sound and they are quite when not under acceleration or decelleration

Does it have that grumble in idle?

[Brutus]

I had the 40's put on mine with the stock tips(resonators). I am very happy. Alot better sound but not too loud. I heard a buddy who had the same put on his mustang and it had alot of resonance at 2500-3000 rpm's, however with the stock tips its not a problem. Thats my 2 cents.

RA554201. All Ravin turbo mufflers are made to the same specs, the difference between 33s, 55s and 77s is length and pipe OD.

Well, yes Reap, they can grumble at idle, or not, with "Wes Chain" tips installed. Remove the resonator from the factory tip, and you will learn how to control the exhaust tremble at idle with a form of light brake torque, so, realistically, you CAN have it both ways. Quiet, or, intimidating.

I would like to add that by the time you reach 4000 RPM in WOT, the engine is making more noise than the exhaust, including a straight pipe setup. I tried this myself, and found it much too high pitched on resonators alone. Kind of like a two stroke motorcycle compared to a four stroke, more whining than chest beating thumps. After all, it's still a small block 281 CID, and there is only so much "grumble" in the small bores...IMHO.

[Marauderman]

Well, All I know is --I just put on headers with an x-pipe with the "straight" Wes Chain clear tips and still kept the OEM mufflers-- A N D -- The sound it now produces is like no other MM I'ver heard yet--completely different--louder and at high speed, it back downs with a rumble that makes me smile --almost like a "JAKE" brake on tractors..it's awesome..and a much more rumble--there is instant rumble recognition at any RPM level--so for now--I've skiped the idea of Flows and now moving on to brakes--cause this bad boy just got a whole lot faster as well with this newer mod...so much infact--that I had the OEM brakes burning trying to slower her down in a hurry from 110MPH this
weeked ...so brakes upgrade is deffinitely next for me....my .02 cents worth...

[studio460]

I'm with Reaper . . .

Looking for LOW FREQUENCY rumble both at IDLE and at SPEED. Ever hear those 4.6L Mustang GTs (with modified exhausts) tooling around with that MEGA-LOW rumble? They show that our 4.6-liter powerplant is very capable of sounding very 5.7-literish. Even a stock Mustang GT exhaust puts out damn good low frequency rumble.

I've listened to the Ravin sound file, and it sounds a bit too high pitched for my taste, IMO. No telling how representative the sound file actually is . . .

So . . . for any of you who have heard Sarge's (or anyone else's Marauder) with Ravin 55s, side by side, to another Marauder with Flowmaster 40s . . . Which had the lower frequency rumble?--I've already got the resonatorless Megs tips sitting on a shelf waiting for me to make a muffler decision. If you're looking for that low rumble, vis-a-vis, Camaro-SS-with-SLP-exhaust kinda sound . . . which would you all recommend? Thanks.

[SeanM]

Reaper,

I put the Flowmaster 40's on my MM and they sound great. But just so you know, the actual name of the mufflers is the Flowmaster 40 Series DELTAFLOW. The regular 40 Series are much too loud INSIDE the car and are very annoying when you want to hear the radio or a passenger. The Deltaflow keeps the sound outside the car. I used the 2 1/4" Center in Offset out mufflers and they had no trouble making them fit. Good Luck. You'll also want to swap out the tips if you really want it to sound mean. That's my next plan.


Sean

[studio460]

I FINALLY got my mufflers AND my resonator-delete tips (which have been sitting on a shelf for three months) installed!!! The shop insisted that I'd like the Magnaflos better . . . I DIDN'T!!! Well they put the Magnaflows on anyway in my absence, and well yes, they sounded nice under throttle (albeit, on the QUIET side), but they were SILENT at idle and deceleration. Well, to me, "better" is LOUDER, and I said, "I want the Flowmaster 40 Deltaflows!" So they took 'em off and put the Flowmasters on.

So now I have the Flowmaster 40 Deltaflows with my Megs resonator-delete tips from Cone Engineering (purchased right from our site sponsor, Innovative Interceptors). I also had the shop extend the tips out about 1-inch. The car is now loud, beefy, and you can hear it rumble at idle. And lemme tell ya . . . it's swweeeeeeeeeeettt!!!

[Sidney]

I have the flowmasters also, and they sound so good at startup. However, at about 2500 rpm they really scream and sound like a mustang.

[studio460]

Sidney:

Yup, that roar at start-up is GREAT, isn't it? THIS IS EXACTLY THE SOUND I WAS LOOKING FOR!!! It's between a Mustang GT and a Camaro SS SLP exhaust sound (both of which I love). AND, you can hear it at IDLE! The sound is rich, low, booming, and LOUD! Yup, loud and gutsy (not "tinny" at all), but doesn't set off car alarms like the Camaro's exhaust. Pretty darn quiet inside at 2,000 RPM, too! Loud as Hell inside at 1,400-1,800 RPM, but that's exactly when I WANT it loud inside!

[DetGeno]

Hey NBC can you share with us the cost break-down on your mufflers and tips?

[studio460]

Well, that's a looooong story, but I'll cut to the chase. One shop quoted me $250-$300 for the two Flowmaster 40 Deltaflows, muffler install, and tips install (already had the tips). Instead, I went to another shop, a well respected muffler shop (featured in Mustang Monthly, etc.) and had a less than perfect experience. I'll detail that whole story in another thread.

Anyway, I was willing to pay more for a really clean job--that's why I went there! That shop charged me $300 "parts" and $60 "labor" bringing the total with tax to $384. And I didn't get the job I was expecting either. Plus, there's a hole in one of the welds I just discovered tonight after inspecting the job. Again, I was willing to pay extra for a perfect install, but this experience was far from that.

Another shop I called previously wanted $80 each for the Flowmasters. Don't know how low you can really get them for. Anyway, I think around $250 (or less) including parts and labor is probably fair.

[martyo]

Hey Sidney: We haven't seen you around much. Are you going to join us in Texas??

[Sidney]

I have just been floating around in the background and learning alot from you guy on the site. I am going to try and get to Texas cause it seems like it going to be alot of fun. This is the best way one can compare mods and make decisions. The website and you guys are wonderful. At the tender age of 29, I am just sucking in all this great knowledge. Hope to see u in Ennis!

Sidney...where from? Macomb county here. You are welcome to convoy down with the Michigan guys/girls going to texas. I even have an extra reserved room at the host hotel in Ennis.

[DetGeno]

Can anyone tell me exactly what FlowMasters can do for our MM? Does it just sound better? Or it actually increase the flow and give more HP? Thx!

[DetGeno]

If all Flowmaster does is to sound better, I am not going to get it. I like to sneak up to the individual when I have a property seizure, writ of execution, PPO or subpoena for them! In fact if I ever seize a MM, this board will be first to know it. Because I can't buy it myself!

[studio460]

Well, without a dyno, there's no telling . . . Make sure you like loud if you get the Flowmasters--they're LOUD! In fact, I could swear I LOST torque/horsepower from 2,000-3,900 RPM. Could that possibly be just a tuning issue to accomodate the O2 sensors' seeing the increased air flow? Anyone ever hear of needing to re-tune due to freer-flowing mufflers?

[Sidney]

Did you disconnect the battery for the computer to pick up the new flow (about 35-40 min)? Otherwise it may take a some miles for the computer adjust. When I had mine on the dyno, gained about 10 foot pound of torque. This was from about 3000 rpm. Will be getting another Wed. and will try to post. Jerry will be there so maybe I can get a dyno on the whole rpm band.

[studio460]

Sidney:

Thanks for the disconnect-the-battery tip! I disconnected it for 45 minutes--MUCH BETTER!

I agree. Although, I wouldn't necessarily call it a "scream," it's more like a ROAR!!! Nice FAT sound waves from 1kHz-5,000kHz!

Welcome aboard!

And good luck...there are only about 100 or so folks in CHI-town. They have their own area here on the board under the Forum "Windy City Marauders". Good folks up there with lots of info for you.

Just watch out for a guy named Zack...:lol:

[cstringe42]

Todd,

Thanks for the welcome. I will definitely check them out. This site is great, full of information and good people.

Where exactly are you located?

[cstringe42]

I'm in Rockford. Some around here just purchased a blue '04. But I spend a great deal of time in Chicago. Ride through Elgin all the time.

[murray]

:confused: SergntMac;how do you remove the resonator from the stock tips?

[MAD-3R]

The tips are out right replacements.

[WolfeBros]

Murray,
I can answer that for ya. You really can not without tearing up the tips themselves. The good news is the same company that made the OEM tips, Cone Engineering makes the Marauder MEGS tips w/o the resonators in them. You can get them from Innovative Interceptors. Wes is a vendor on this bbs and he will be glad to help you. Several people on here are now running with these tips.

[murray]

:beer: Thanks folks for your quick responses.

[WolfeBros]

Hey Murray your welcome. Thanks for stopping in at good ol' MM.net :D

[deerejoe]

Have just spent considerable time with the Flowmaster factory rep. by telephone...they are not up to date on the MM...BUT,
we discussed several issues...(including the Delta 40 Series). One issue being the tips sans resonators to which he did NOT endorse due to "ambient drone" at 2000-2500 RPM (too pervasive). This is common to MOST applications...he assumed the customer is looking for the Mustang sound, etc. in wanting to eliminate the resonator tip.

It (the drone) becomes overwhelming on long trips and incidentally, makes women grumpy!! Whoaaa.....

I mentioned our website and requested his R&D group "look into" the MM and learn the specifics to our cars. He was impressed by our knowledge and willingness to explore the after-market options available in general.

I beleive it is worth considering the amount of exhaust note (you want) given with each specific system before commiting to the expense and end result.

As an aside to this information; during the discussion, I learned that the Flowmaster muffler installed on my Hemi Pick up is NOT the correct unit for it!! I am now obliged to try and have the proper unit installed after accumulating nearly 5K miles.

Just an FYI for those of you still speculating about exhaust mods, etc.

[bryanknie]

I got the "original" flowmaster 40"s on mine, which are louder than the "deltaflow", I love the sound with stock tips, a little rumble at idle, a roar when you go down the road. They are a little louder than stock on the inside especialy at 1500 to 1800 RPM, but I dont stay there long. at cruising speed of 70 - 80 they are quiet on the inside and very swweeeet on the outside. Paid $180 including install at a local shop, they did a great job, welded them on and added hangers that bolted on to the stock location.

[studio460]

INTERIOR DRONE/SOUND CHARACTERISTICS:

I had the opportunity to drive my Maruader with two different brands of aftermarket mufflers installed. My Marauder is a 2003 300B with 9,000 miles, with no other mechanical mods. Both sets of mufflers were installed with Cone Engineering's resonator-delete Megs tips. I've also added my own subjective sound scale ratings.

1. 14" Magnaflows:

To the best of my memory, I sensed moderate to significant interior drone from 1,800-2,200 RPMs at typical freeway speeds from the Magnaflows even though these mufflers were much quieter (exterior) than the Flowmaster 40 Series DeltaFlows.

14" Magnaflows w/resonator-delete tips sound characteristics (exterior):

LOUDNESS UNDER THROTTLE = 7 [Mustang GT = 8 Camaro SS/SLP = 10]
LOUDNESS UNDER DECELERATION = 1
LOUDNESS AT 10 MPH = 1
LOUDNESS AT IDLE = 0
LOW FREQUENCY OUTPUT = 9
RASP = 0

Note: Get these if you like loud ONLY under acceleration, and quiet at other times, and no sound at idle. Oh, and don't mind drone.

2. Flowmaster 40 Series Deltaflows:

After expecting a increased interior drone with these much louder (exterior) mufflers, I was happily surprised to hear that they were actually QUIETER than the Magnaflows at the most CRUCIAL RPMs!!! While cruising at 2,000-2,200 RPMs (e.g., at 70 MPH freeway speeds), they're nearly silent inside the car. If there is any increased drone, compared with the factory mufflers/tips, it can't be more than a 10%-15% increase, if any, at this RPM. Now at 1,200-1,800 RPMs under mild throttle, there is a ROARING drone both inside the car and out--but that's where I WANT it LOUD anyway!

Flowmaster 40 Series Deltaflows w/resonator-delete tips sound characteristics (exterior):

LOUDNESS UNDER THROTTLE = 9 [Mustang GT = 8 Camaro SS/SLP = 10]
LOUDNESS UNDER DECELERATION = 5
LOUDNESS AT 10 MPH = 7
LOUDNESS AT IDLE = 4
LOW FREQUENCY OUTPUT = 9
RASP = 2

Note: Get these if you like LOUD, plus sound at idle.

[jaywish]

Hi folks,

You all know it takes all kinds.... so get ready.

I was thinking about taking off the tips and simultaneously quieting down the exhaust.
I like fast but quiet.
Low key is me.


From reading the posts:
I think the tips themselves are removable. (bolt ons?)
As the tips are resonators the removal may produce cruising speed droneing.

I haven't seen any posts about quieting her down in general.

For instance, could a police muffler be installed on these pipes?
Are the police ones any different than the performance pack ones?
Pipe diameter issues?

[MI2QWK4U]

I went with a cat back system. Started out with a 2 1/4 inch custom X-pipe into some big Magnaflow high flow mufflers into my pre-production MEGS tips w/out the baffles. It is the first setup like this im aware of and the sound is sweet. Very low bauble and rumble, cabin noise is not much different, but it sounds stronger rolling by. I was worried about the Magnaflows, since they are a straight flow through design, with no baffles or chambers, would be too loud..but they werent. I am very happy with the performance upgrade and the sound.

I'm new to the drag car scene and have a stock exhaust on my Kenny Brown car.

I don't want anymore noise than I already have at normal highway driving speeds. But I want to extract more power from my MM. I don't care about the noise level when I'm under WOT.

Unfortunately, I'ld like to drive one of these "Kooks exhaust" cars with my meter to scientifically determine if there is more noise or not. Otherwise it is all a matter of each person's sense of noise level. Once I modify my exhaust, the last thing I want to say is that it is too noisy.

I know the answer. I 'll have to come to the next maraudeville event. Then I can drive (if he'll let me), Logan's car with his Kooks exhaust or other willing car owner.

It seems like I'll have a long drive from Massachusetts to any of these events.
