I just replaced my stock exhaust header/manifold after finding cracks all over with another stock manifold. However, I installed a Magnaflow High Flow catalytic with a Flowmaster Super 44 muffler and it sounds awesome! Very throaty, deep tones, a little crackling on de-acceleration and slightly louder than tires and noise on highway; doesn't over power stereo.

VERY HAPPY with sound, a [slight] performance improvement and appearance.

Cut off the tail pipe and put a turn down directly behind your muffler, you'll like it and it's a cheap upgrade to what you allready have.

Excuse my slight ignorance, can you be a little clearer what you mean by a "turn down"? Do you mean to cut it off after the catalytic and reattach to come out under or before axle?

Thanks!

a turn down is basically a short downward facing pipe attached to the outflow pipe of the muffler. basically you dont have a tailpipe sticking out of the back of the jeep, the exhause ends after the muffler

the only real way to get a great sounding exhause, not just a loud muffler sound is by doing the whole set up...headers high flow cat and 2/3 chamber muffler or like a magnaflow straight through type muffler

Exactly. If I could get quiet and not lose power I always would do that.

Generally speaking the worst thing you can do for performance is to change the length of the pipe in this manner.

The pipe length is criticle in the harmonics of the exhaust system to help the cylinder scavenging of burnt exhaust gases. By changing the length the system is ruined and you end up with burnt gasses in the chamber which means two things, more heat is the first, the second is less room for fresh air which has burnable oxygen.

For that reason I usually avoid chopping exhaust. Now if you're turbo then none of this is true as the turbo itself mostly stops the harmonic wave of exhaust but makes up for it by spooling the turbo.

I currently have a flowmaster installed on mine by the p.o. I just cut my tailpipe off behind the muffler and didn't loss any power. It definately is louder now. I have a banks system and a free flow cat to install as soon as I get my rear suspension tweaked exactly the way I want it.

I had a flowmaster 40 for a while and it sounded ok at best. It also was really loud in the cab and became very annoying. I now have a SpinTech Prostreet 6000 series muffler and it is great. It sounds amazing and really mean. Best part is it doesnt drone in the cab at all. I have had several people ask if I had a V8 under the hood.

Agreed, but there's budget constraints :-(

So I kept the stock exhaust Manifold and went with everything else. Loud and not annoying in my opinion. Had my mountain bike in the back with the hatch open and it was even louder to my surprise, which gave me a better idea of what it sounds like to others behind me... sounds like a 302 Mustang with flows! ;-)
