My 4.7 has a flowmaster on it. It is actually really quiet. I am not sure which flowmaster it has on it as it was already installed when I bought the WJ. It has a good sound to it, but not nearly as mean as the sound of the ZJ with a flowmaster. The ZJ sounds way better.

My brother in law had a magnaflow and a nice tip on his 4.7, and it had a mean growl to it. I have always like the flowmaster though, but this is because I like the way they sound on my Camaro. I usually can find them for around $80-$90 at a local exhaust shop.

2.5" Carsound cat, Flowmaster 70, factory stainless 2.5" mandrel tailpipe on 2001 WJ 4.7. Sounds good, not too loud. Been running this setup for 80,000+ miles.

i just recently put a flowmaster 40 on, i love the sound around town it sounds good and turns heads, on the highway, its not too loud, which was surprising to me.

I cut my factory muffler off and welded in a straight pipe with a 3 1/2" stainless tip...i love the sound and it cost me a whole 25 bucks. I have so many people stop me and ask what motor and exhaust i have on it...everyone tells me it sounds like a LS1 T/A.

I had a flowmaster 40, it sounded great, boosted the power too. But now since Claytons is on my WJ i had no room for the 40. I have a hushpower on it now. It is a little noiser but performs good, plus it's stainless. Good luck.
