3.5" Exhaust, Will It Work
Will be pulling the trigger this coming week on a set of stage 1 injectors and a chip for them. Already have on order a G2 w. wheel, turbo rebuild kit (don't believe I need it but getting it in just in case), up pipe gaskets, exhaust manifold gaskets, glows, uvch's, gauges.
The after turbo exhaust is factory 3.5" no muffler but it ends just behind the passenger door out the side.
My question for the exhaust gurus is, Do I need to size it up for the larger injectors, even when it is so short a distance from the turbo?
I understand the basics of fluid dynamics (yes air is considered a fluid) and that bigger is better for after a turbo. I just wonder if it is necessary for a larger pipe in my application. I guess the temps will tell too. I don't want to blow the $$$ on something that isn't absolutely necessary.
