Muffler thoughts?

What muffler is everyone running begins their 4.0 I'm lookin for somethin not to laud and obnoxious but still a deep throaty sound. A thrush turbo muffler sounded good on my buddies. Thoughts? Flow master?

I don't know where you live but in NC you don't have to have a cat on anything 94 and down. So I've got a 91 and I run a flowmaster 40 straight to a down pipe. It gives a great sound and not annoying at high speeds.

I was wondering this as well. Not sure I would hear anything over the roar of the tires though. ;-)

Have a Magnaflow on my stroked 4.0 with straight pipes and it sounds quite nice.

I have a flomaster Super 10 series on my jeep and a high flow catalack. The super 10 is the loudest muffler flomaster makes. Its about 1/2 the size of any other muffler.

I had a Magnaflow 16" 2.5" I now have a Flowtech 20" 2.5" and think it is perfect. It does not have any Fiber Matting inside it, just chambers. Sounds low, deep, and throaty.

Meh on magnaflow or flowmaster mufflers. Gold-chain, Bro-tastic crap.

For a classic six-cylinder sound, get one from an early 6 cylinder Jag.

For a classic hot rod sound, mount a cherry bomb backwards.

Mounting one with the internal louvers facing the rear provides a louder, raspier sound and is best for high-rpm motors.

Pointing the open end of the louvers forward ('backwards') provides a low, throaty rumble and is better for a low-rpm engine, as in a Jeep.

Magnaflow 15160 axle back duals....awesome look and sound! I just installed yesterday and love everything about it. I am not a speed or power freak but; I definitely feel a difference in torque and acceleration without "stepping" on it. Here are before and after pics
