Stock s4 na exhaust manifold max hp flow with 2.5" back piping ?
I was thinking of just using the stock manifold and getting all piping from the manifold flange back , pretty much all straight flowing exhaust with no cat and a 4" tip
streetporting is done on it , functioning 5/6ports using rpm switch, also gonna get an safc
im hoping to get 170whp with this setup is it possible or am i pissing in the wind ?
id rather spend less money and not get the header ( header is 200 bucks f' that)
