The 08-10 Subaru WRX GrimmSpeed Up-Pipe is made of 304 stainless steel and has a pipe-wall thickness of 14 gauge, this is the most "heavy-duty" pipe you will find. The inlet size is 1.92" and the pipe tapers down to 1.72” which acts as a funnel as it moves into the turbo allowing for the smoothest transition and best air-flow quality. The triple layer flex joint is not located in the bend, which adds to the life expectancy of the flex section. The outlet size is a perfect match to the most common stock location turbos allowing for a smooth transition into the turbo.
