If I were to put a 3 inch dwnpipe connecting to my 2.5 exhust will this be any more restictive than just haveing a 2.5 in. downpipee? I want to leave the option of a 3 in exhust later.
Also what do you use to connect all the piping such as downpipe to exhust and all intercooler piping? Not welding it, can you just use silicone connectors and a circular clamp? (Like on a CAI?)
Any ideas where I could get cheap turbo manifolds or a downpipe. It doesnt have to fit as I would just have flanges welded on.
If I have an fmu, and a b&M fpr, is there a need for bigger injectors for under 10lbs of boost? Inline fule pump?
What are the ratios for on an fmu(12:1, 10:1)
Sorry about all the questions Im just trying to learn as much as possible, and I searched each one first.
