After I complete the b16 swap I want to have the exhaust done at a shop. I was thinking of going with either a 2.25" or 2.5" dynomax muffler and piping with a high flow cat. Which is better (2.25 or 2.5) for this engine? I was thinking of going turbo eventually so would 2.5 be ok? My only question is whether there will be enough back pressure. I know little of this subject and your imput is greatly appreciated --Thanks
