What do you guys think about a super 44 on a 4.0? How would it sound? Would it affect gas mileage?

I love mine. Super 44 on a 01 4.0. Had it dumped for a long while, then did new piping with 2.5" incoming pipe and dual 2.25" tailpipes. You won't gain mileage, and you won't lose mileage.

Yeah i was just checking to make sure I wouldnt lose any mileage. And how does it sound? Is it a nice deep rich sound? Btw i love ur truck its sweet!

If it sounds good on my 3.0 with just a MAC Performance intake then it will really sound good on a 4.0! It dosnt pop on mine or anything, not even reving at the redline. It has a true gurgle sound to it. If I were to describe it furthur, it allows the true muscle sound of your engine come out without the crackles. Its the perfect muffler.

deep, beefy, loud on the outside, quiet on the inside, very little drone, it's a powerful sounding muffler under acceleration, and tame on the freeway. I love it.

Ok sweet that sounds awesome. Deff on the project list. I have a glasspack now and its nice and all but it has popping and cracking when reving.
