what about a custom 3'' exhaust on a turbo car? straight pipes... my friend has one on his mk3 supra... he got all his parts from jcwhitney... i think it sounds like his car has bad gas... like it farts too much kinda bad gas... should i expect this out of a straight piping custom exhaust on a turbo 4? im debating weather i should go through with it... i though i could cut corners on the exhaust.. but im having second thoughts... haha i guess what im getting at is does the exhaust matter on a turbo 4 cyl as long as its 3'' piping? will i feel a gain in power or lose depending on company and what not?
sorry if thats a dumb question.. im still trying to learn...
