Muffler Advice 4.7L
 
Anybody know of a muffler that sounds mean at the higher RPMs but doesn't have the annoying drone at lower/medium RPMs? Something to make my jeep sounds vicious but not annoying for long distance.

I have a flowmaster 50 and it is pretty quiet until I step on it. I know a lot of guys around have the 50 and love it.

I've read a lot about the magnaflow but all the videos are only when people are flooring it so they don't really help. I'll look into the flowmaster though.

This is magnaflow 18".... kinda bad drone at 70mph. Id get the 23inch instead personally.

I had a pair of Magnaflows on a Mustang GT a couple of years ago and they were just what you're looking for. Try this site for exhaust sound clips:

most a/m mufflers are gonna give ya massive drone without a resonator. Talk to sleep4.7 or search his posts for 4.7 muffler recomendations...or I like the no muffler and resonator only setup on my Jeep...and it has 0 drone

I run a 18in magnaflow on my 4.7, it sounds really mean when I get on it and its quiet for daily driving, it does drone around 2k but I think you will get that problem with most mufflers if you don't put a resonator on. It doesn't bother me, and for the $105 I paid shipped for a stainless magnaflow it was well worth it.

I've got a fm delta 40, drones like a biatch, but I've gotten used to it, sounds awsome in my opinion.

Flowmaster 50 series SUV performance is the best IMO.
