Dont mean to take over the thread but, what did the vortex muffler sound on your 4.0? Ive heard the extreme muffler on a 3.0 i think, and it sounded pretty rugged. Obviously with the 4.0 it would sound even more so, better i assume?
well i have the super 44 on my truck idk why but its about an inch longer then my old original 40?? the sound is softer then the 40 but better sound at idle but driving i cant hear it as good idk why but i do wish i baught a 40 again.
Super 44 is deeper, more powerful sound compaired to my Super 40 I had AND the Original 40 I had.
My Super 44 is dual out. All my others are single out...might make a difference. Actually.....i'm starting to feel positive about this....dual out dumped is effin' hella sick sounding compaired to single dumped.
I'm still going to run tailpipes on mine though...most likely.
