X Pipe Question
We are getting ready to cam and put headers on my 07 z51. I have a quick question. I have headers end in 3 inch. We will be running qtp cutout back by the transmission. I plan on running no cats.
My question is if i was to make a short "test" pipe to go from the 3 inch down to the 2.5 stock x pipe would it really make that big of performance difference. It will only be about 3-4 feet of 2.5 before the dumps. Or does it help to have 3 inch all the way back?
Would it be a huge difference I have the flanges and pipe just have to weld them up to make the 3 to 2.5 but if it makes that big of a difference Ill just get a 3" x pipe
