I have a glasspack on mine and I love it! But when I ran straightpipe for a week or so it was loud as hell!!! I like loud but Jeeps need mufflers to sound right

If it's free...take it and try it. If you don't like it, you're only out a little time and effort.

I was happy with mine when i had it straight piped all the way back with a stock tailpipe. Only reason i got a muffler (Flowmaster Super44D) is i have night classes and i don't wanna be that guy who drives a loud car through the neighborhood at 10pm. No clue how it sounded behind at higher RPM but it sounded awesome idling.

Had a Thrust glasspack, hated the way it sounded and it was a pain getting the tailpipe to line up.

I have a pack on mine and it was quieter than I thought it would be. Makes good tone but it doesn't sound like a V8

try it. if its to loud with just a down turn run it out the back it will even the sound out and increase torque
