Let me know about clearance issues and how you like it...

Thanks!

I've got sportlines and clearance with headers is tight. ~3 inches of clearance all the way back, ~2.5 at collector flanges, ~2 where the the y pipe has to clear the tranny Xmember.

Better be some skinny duals

Probably a good candidate for an oval exhaust setup.....

Yeah I figured it would be pretty tight with a Y-pipe (depending on its diameter) I currently have a 3" custom Y-pipe off of my TPiS LT's and clearance is already pretty close with stock ride height. That's why I was asking about 2.5" duals since it'll obviously be deleting the Y-pipe route for an X-pipe (which should help)...

How about someone with the Pro-Kit and 2.5" duals?

Pro-kit would be better for duals. I love my sportlines, but WILL be going to the pro-kit for that extra .75" clearance. Makes it easier to go all over the place, especially over the oil bay rails at work. Might want to consider some chambered mufflers, since they're not any fatter then straight pipe

ive got em and my clearance is fine. my exhaust is the optional 3" cat back from SLP(still have the dual cats on). i did swap out the SLP power flo muffler "2 on the left" for a 3" in 3" out single chamber flowmaster. its really small and is tucked up reall tight. you can barely see it from behind.....

i do however want to strengthen up the rear end now.....i see some companies have the lower control arm relocating bracket that is supposed to fix that problem....anyone know????

I have intrax 2 in drop springs, with jet hot long tubes and true duals that dump before the rear 2.5 inch round pipe.

The only problem i have with clearance is huge speed bumps, other then taht nothing.
