I'll right to the chase, would putting the corksport exhaust on an n/a result in a loss of power due to its size or adversely affect the opening of the 5th and 6th ports (on a s4)? i'd rather get the apexi gt spec, but am worried that will also adversely affect the engine due to pipe size. are there any single exhausts on the market for a decent price that aren't overly high-pitched?
