Have you driven it in 4th gear at about 60 MPH yet?

You still have DOD enabled? If so this will probably make you want to turn it off....lol

Oh the chopper lol yeah I've heard it.. Getting a CAI first then tune!! So I'll remove it then!!
It's a tad too loud but oh well.. Haha it's still pretty nice sounding!! Better than buying a quiet cat back :) can save the money for drag radials!!!

And joe!! No we cut the mufflers out, ran two straight pipes and tips.. Ending up with 2.5 pipes.. Don't ask.. Lol but bought extra pieces to make it fit.. Somewhere oblong said our exhaust was 2.5.. NOT TRUE lol

Sounds bad ass man! Ahhhh the good ol' sound of a v8 with nothing but straight pipe exhaust.

i believe it might be 2.5 inch up to the Y pipe than smaller maybe 2 or 2.25 to each muffler?

sounds great. but attracts WAYYYYYYYY too much attention from police.

After the res I'd say 2- 2 1/4.. I got three inch after it Ys.. Had to use 4 extra fittings but the 3 inch gives a beautiful rumple-crackle letting off the throttle at 3000+ rpm.. Cabin is hell lol i drive with rear seats folded down for my system but they immediately went UP haha

2.5 I mean!! Is what is ran now

I deleted the resonator and had Magnaflow mufflers with custom 3" from my dp back and it sucked on the freeway. I can't imagine having no mufflers! Yikes!
