Magnaflow Mufflers

[Woodykylite]

I really like that deep bass growl sound on Chip Foose's Overhauled hot rods. He usually put's in maganaflows on hotrod overhauls. Can this be achieved by switching out the 2 stock mufflers and putting in magnaflow mufflers. I like the magnaflow sound. Has anyone done this, and if so what are the specific dimensions that I would need. I don't want to change out the whole exhaust system that's why I was thinking of just switching to magnaflow mufflers. It might not even be possible.

You can increase volume and sound, but "deep base growl" and a 4.6L DOHC engine don't really go hand in hand; you want that sound, you prolly need go to a larger displacement pushrod V8... ;)

Isn't that what magnaflow is known for "that deep bass growl"? Spell check got me again.

18 inch ones will probably be closer to the sound you're looking for, but not that big block sound, since these motors are revvers.

Yeah, but you've got to have an engine that will generate the sound for the mufflers to work with. The 4.6L DOHC engine doesn't sound the same as, say, a cammed BBC.

That said, Magnaflows, rear cat delete, and resonator delete tips will make your car sound louder and meaner, but not necessarily like a Foose car.

Bare with me because I'm new to all this stuff and want to be led in the right direction. But what size magnaflow mufflers, what does rear cat delete mean and and are resonator delete tips a brand, and if so what size?

[1stMerc]

Get in on the coneeng group buy for the 4" res delete tips. That's one step in the right direction.

Look inside your stock tips and you will see the resonator. The ones being offered don't have it and the opening is larger.

[MrBluGruv]

Larger diameter piping will also make a difference for a deeper, more bass-rich tone, but as was already stated, this motor isn't one that is naturally deep in tone.

I think will do the 4" res delete tips

So magnaflow mufflers would probably be a waste of money without a bigger motor and or thicker exhaust piping.

[1stMerc]

If you haven't already done so, attend some local/regional events. You can get a diverse sampling of pretty much all that has been done to a Marauder exhaust wise. Nothing like hearing them in person. Willing to bet all will be glad to talk about what they've done to acheive they're particular sound.

Not at all. The packing material inside the mags plus the larger piping and delete tips will lend to a deeper tone as oppose to the all metal componetry of the others. I would also say keep the H pipe.

We love to talk about what we've done to our cars, eh Rex.

BTW, i forgive you for beating our Rams :(

IIRC it's the 18" case 2 1/8" off center inlet by 2 1/8" center outlet. Probably have to go with 2 1/4" and just weld them in.

Rear cat delete = cut off the rear catalytic converters and replace with straight pipe. Your computer will not know a difference and no tune required. Most shops have no problem doing this and most pay around $30-$40 for labor and material.

Hope this helps.

Thank you for taking the time to help. Just to make sure,The first dimensions are for the magnaflow mufflers? I'm going to go onto their site tomorrow and get the correct materials.

I have the 18" Magnaflows. Good sound but not a BBC. Also have 2 1/2" all the way back, X pipe, no Megs deletes, & and no 2nd cats, with a stroker motor

[boatmangc]

I like the way my Magnaflow 18s sound, 2 1/2 mid pipes with no cats, shorties, stock from the mufflers back, even stock tips.
Much better sound, deeper and meaner when you step on the loud pedal.

Yes, I wish there were more videos examples of this on YouTube. I could only find a couple.

Exactly what I have in this video.

We did a LOT of experimenting with my exhaust......first just Magnaflow 18's and it was deeper but very quiet (the SS packing does go away in time but couldn't wait) so we took out the H-Pipe next and replaced with an X-Pipe and it sounded way too "ZIPPY" kind of like 2 mad Hondas with "fart cans"!!:argue::mad2:

Next we went with a nice larger H-Pipe with 2 Hi-Flow Magnaflow cats and BINGO.......to me it was perfect......still have the stock tips and exhaust manifolds.....ZERO DRONE too...after adding the CV exhaust dampers!!:beer:

As stated before....Magnaflows get louder in time.....almost 7 years and 160,000 miles later.......JUST RIGHT!!:D

[J.bo]

ZERO DRONE too...after adding the CV exhaust dampers!!:beer:

What is CV exhaust dampers? You have pics?

[Marauderjack]

They are weights that bolt to the flange where the down-pipe meets the H-Pipe.....left and right sides are specific!! Can get them from any bone yard that has Cop cars.....CHEAP!!

The Marauder had them welded to the OEM mufflers......TAF at Grand Muffler told me to lave them off but they really help subdue rattles and drone......believe me....all my noise in now.......OUT BACK!!:beer:

I have a photo somewhere if you need to see 'em??

Here's the right side one .......one for each side!!

[WhatsUpDOHC]

Interesting. Like sound dampeners.

BigCowl- Do you have any of these?

Vibration and harmonic dampers....they work for drone and exhaust rattles!!:beer:

If you scroll down this sub forum there are before/after video's I took of the 14" magnaflows I installed.

Sounds like CVPIs.

Why do LEOs get all of the goodies?

Here's a link to my MM with Magnaflows:

http://youtu.be/nCp8XtARpe0

[GreekGod]

I just had my MM on my new hoist, and measured for mufflers. My (still OEM) 2003 has 2 cat converters on each side, and 4 O2 sensors (front & rear on each side). The mufflers are 21" long, ~10" wide, & ~6" thick/tall. The system is 2 1/4" od until it gets to the H-pipe, which is 2" od, and the (smooth bend) tailpipes are 2 1/4" od, to the resonator inlets. The muffler inlets are offset, and the outlets are centered.

I used Magnaflow #12256 stainless mufflers on my 2000 Crown Vic. They are 2 1/2" inlet & outlet, offset on one end, centered on the other, and can be installed to flow either way (reversible). They measure 18" long, 8" wide, and 5" thick/tall.

I recommend you only change out the stock mufflers, and use the (2 1/2") #12256 Magnaflows. It is a simple job for any exhaust shop, and the Magnaflows will fit, with adapters, which any shop can weld in. They are fairly quiet, and will still work/fit later if you go with bigger (2 1/2") pipes. By modifying in stages, you can see how you like the sound, and make it louder as you go.

I'm 61 years old, and prefer a not-too-loud system. Especially so as not to attract the attention of officer friendly.

Mind you these are both P71's,NOT MM's.

Which Magnaflow mufflers are these?

[breeze]

http://m.youtube.com/index?&desktop_uri=%2F#/watch?v=9fzfUYVEiKk How do this sound to ya?

[tbone]

I loved my steel Mag's when I had my OEM exhaust. Lots of compliments. Stainless Works muffs are very good in their full system with headers, but I think stainless Mag muffs would sound better. Will switch back when $$ for stainless Mag's is available.

[71cyclone]

Yeah, but you've got to have an engine that will generate the sound for the mufflers to work with. The 4.6L DOHC engine doesn't sound the same as, say, a cammed BBC.

That said, Magnaflows, rear cat delete, and resonator delete tips will make your car sound louder and meaner, but not necessarily like a Foose car.
Good note ## I had the Magnaflows installed along with 4' tips , real nice sound over stock. later had the rear cats removed .The car had a Bass' sound at Idle and a loud rumble when stomped on. , the drone was annoying so I removed the Magna's and put the stock Muffs back on.
I have since installed an X pipe system that lowered the exhaust sound, and noticed better mid range and top end performance, I later observed 142 mph in drive ,over drive was turned off Rpm was past 5000 with 355 gearing:burnout: Reinhart Tune with a minor 2 degree tweak and shift adjustment
