ya thats sounds good.. muffler dumps are good thats how mine are headers to y-pipe to muffler with downflows! u dont need to x or h pipe ypipe will do just fine mine is 2.25-2.5 exhaust size

 

Ive got a thing for the X pipe not sure what it is, but I really want it haha.

 

2.5 all the way through on mine. You want the flow yes but you also want some back pressure too, personally I see true duals more as a bragging right. A good single 2.5", ceramic coated pipe, exhaust would serve good for years as well as save on cost. You can also get a good sound out of a single too depending on your muffler choice.

 

Ya screw duals lol and im gettin an Aero Turbine 3030Xl lol they sound good, I think anyways and the headers are ceramic coated but I doubt ill have ceramic pipe all the way through. The pacesetter headers (long tubes) im lookin at are 1 3/4.. can I get 2.5 pipe followed by the headers all the way through?
