Intermediate Exhaust Pipe Sizing - Does it Matter?
So, I recently replaced my intermediate exhaust pipe with an Omix-Ada that was basically the same shape and size as the stock pipe. I know that some degree of back pressure is necessary for proper flow, but I was disappointed that I could not find an exhaust with a larger (2.25") diameter. I would like to add one in the future, but my question is: will it make a difference? I have a cold air intake, JBA exhaust headers, and a MagnaFlow performance exhaust, but also a stock intake manifold and throttle body, and a stock catalytic converter...will the exhaust pipe diameter matter without the other factors replaced?
