Re: Help me create a custom exhaust!

Well, im def not an expert on exhaust, but my magnaflow cat back exhaust I have has 2.5" pipes. I almost wanna say the sound you will get depends on the brand/type of muffler you buy. I found alot of good clips of exhuasts on youtube to listen too.

Are you doing this yourself or going to a shop? Maybe go to a few local shops and ask questions, then steal there ideas. Lol. I do that all the time.

Re: Help me create a custom exhaust!

Im looking to add a dual set-up. I want to delete the muffler altogether and install the srt stock resinators, like scott has. I think that sounds sick. Maybe look into something like that. I would just cut out the middle of my WK bumper and install the trailer hitch bezel for the tips, to clean it up.

Re: Help me create a custom exhaust!

it really doesn't work if you want dual put the back, but if you just want true dual exaust then either you'll have to have dual side exit exaust or just put two pipes next to each other at the stock position.

Re: Help me create a custom exhaust!

The shop will most likely be using 2.5" pipe Hector...which is plenty big...stick to the single in and out....its too much money to get duals...and you're very right....almost no exhaust shop wants to do it to a Jeep...

Get this muffler if you want this sound:

Flowmaster: Truckish and throaty, hollow and raspy at times.

Magnaflow: Smooth, mellow, and deep.

Borla: About the same as Magnaflow, just a little quieter.

There are lotsa other mufflers out there, including Gibson, Corsa, and Dynomax, but the 3 I mentioned above are the most popular.

I'd leave the cat alone, unless you just want a hi-flow cat. Then go with car-sound, which is a Magnaflow product I think.

I had a Magnaflow muffler on my ZJ with the 4.0L I6, and it sounded great paired with the K&N intake. I'm running a Magnaflow on my WJ too at the moment, and LOVE it!!

Re: Help me create a custom exhaust!

^^^agree with above, about the sounds from the mufflers from at least what I have heard from friends having them. For some reason I associate flowmaster with trucks, very throaty loud sounding. I think my magnaflow sounds fits more to an suv, def noticable but not like a truck. Scott has a clip of his set-up somewhere on here and I luv it, thats what made me want to delete the muffler and use the srt stock resisnators.

My absolute favorite exahuast is the infinitys, I can pick out that sound anywhere because its so distinct. But I have no idea how to get that sound from mine.
