I believe 2 1/4, but could be wrong.

Try hitting up justbob and/or 1 BAD MERC as they have cut outs.

;)

HPEBadlanz.com Our stock size is close to 2 1/4" like Mike said, they have several different options available for size and mounting.

I got their Custom 2 1/2" dual kit with S.S. Wye's and turndowns.

The Marauder exhaust is NOT 2 1/4. Some is, but its 2" through the mid pipe.

Cut outs are useless. They do 0 for performance and sound like something on the car is broken. They also frequently leak/tick.

They gained 35 hp for me on the dyno when I opened them :eek:

That's your opinion. I love the way mine sound and I am usually using them for drag racing.

In fact when mine are closed I am probably quieter then most of the cars (that dont have stock mufflers) on this site!

Too funny. Someone asks for advice on a product and the opinions just roll on in. Pretty common around here. 😏

35 hp that's crazy where do you have your cut outs located I was thinking on putting them after the manifolds

I have them located right after my SW headers. Not sure a NA stock car would show the same benefits from them.

I know the sc cars show an increase. Plus I am running the crane hot rod cams with my combo which is not stock. So I am not sure you would get the same results with them that I do.

Everyone has their own opinion but they work for me;)

That was the same way I was thinking....I want to wake up the car show crowd when I arrive and then simply disappear on the drive home-relaxed listening to some great tunes!

Just trying to relive my youth but still be able to hear when I got home :beer:

You have a built forced induction car. Big difference to a stock car. You'll see losses across the board on a dyno. (as per OP's mod list)

Cut outs also make the interior of the car smell like ****.

Agreed a forced induction car is a big difference from a stock car and I pointed that out.

A stock car probably would suffer some losses on the dyno but I have never seen a dyno sheet to back that up. I have seen my Lidio dyno sheet that shows I gained 35 hp from opening the cut-outs up!

Now for the quote in red -I would like to know what you are smokin!!!!! :rolleyes:

I have never had a bad smell in my car from cut-outs but I guess if you sit in one place long enough, revving the engine up with the windows down in the garage :eek: then yes you might get a bad smell inside the car!

It is very evident in your posts that you or someone you know had a bad experience with cut-outs and so dont like them. So be it-let's agree to disagree on this issue. all I know is they work for me and I dont have any bad smells. :beer:

^^^^ I like your way of thinking, Brad! :D

I've been considering cut-outs for a while, may have to pull the trigger next Spring if I do some other planned mods.

Yea, Me. When I was 20 and thought it would be cool on my V8 SHO. Open at 7300rpm sounded pretty cool at the time. I've also installed a few in my day on other cars before I had proof at the track they sucked.

I have something even better than dyno sheets. Back to back runs at the track. Before you read remember, V8 SHO's are piles of ****, AND I'm at 7200ft density air. Car had a Chip, Cone Filter, Deleted 3rd cat, and Nitrous.

Exhaust hooked up with Dynomax Ultra flow mufflers.
16.8 @83mph.
Cut out open.
17.2 @80mph.

On the sauce. (100 shot)
14.9 @95mph
On the sauce with cut out open.
15.1 @93mph.

My friends GTO 6.0 (I installed the cutouts on. He begged me to) Mostly stock.

13.90 Stock exhaust
14.20 Cut outs open.

The car smelled like ass inside when I ran the cutout. I wouldn't notice it much until I'd take friends or women out. My car smelt like exhaust inside. Even with it off.

If they work for you, great. You likely don't notice the odor because you either A, don't use them much, or B, are used to it.

You say you gained 35hp. Where in the powerband? Did you get a sheet of open/unopen?

Honestly, I have driven my car to Kentucky (5 hour drive) and to MV 10 and never had a smell inside the car. Could you have cracked a weld or something when you put them on and got a leak in the exhaust somewhere? I know Justbob has them and a couple of more guys do and not one of them has ever reported a smell inside of their cars that I am aware of. We all talk pretty regularly so if there was an issue I am sure one of the guys would have reported it.

Remember I also have pipes hooked up to mine that direct the exhaust and noise flow to the bottom outside of my car.

I am looking at my final run dynosheet and right now cannot find the first run dynosheet that I did. I was standing there at Lidio's for both runs and saw the difference in HP. Also it seemed like the car breathed better with the cut-outs opened. I remember Lidio saying to me when we were looking at the dyno sheets how he could not believe that I gained so much HP with them opened up.

Now I have been told that the intake is what is limiting my car so I am now going to work on that problem next :)

I will then do two dyno runs (probably in the spring) and post both for everyone to see the difference with them opened and with them closed. That should put the debate to rest with a forced induction car.

As for a NA car your experience is a valuable resource for this subject. I cant help but wonder if the altitude you are racing at would effect the breathing performances of your cars in both tuning and running them.

I know back in the 80's I ran a 5.0 Mustang and only ran the cats with the mufflers cut off and straight pipe welded in. The car ran really good until one day on the expressway I sucked the cats out (Heard them go boom!) and the car fell flat on it's face -felt like it would not move at all. That was my first experience with the concept of backpressure and how some cars need a little bit to run effectively.

[justbob]

Zero smells here, even sitting at a light with Long tubes and no converters. But I will agree on real world numbers, but keep in mind my car has no race tune, nor any changes made to the tune for ANY of my exhaust mods.

Dyno results showed a 12 RWHP/13 RWTQ gain, but back to back consistant runs that couldn't possibly been any closer showed ZERO difference. 12.15 open/12.17 closed, both at 111.

I merely went in for an AFR check and a detune if necessary. Boost levels actually didnt drop, and AFR remained completely unchanged. Just a steady rather small increase starting around 2800 RPM's if I recall and smooth and consistent till we shut her down at 6500. Stock block right now and 466 with a roots, that's playing too close for me, that's why I have no issue getting the AFR's checked and see how my gauge is doing on the rollers annually. I also have recorded my compression test results every spring since S/C'd. Over maintain? Yes. I could write a book on the maintenance of my car. 😉
