Alright so I have a 30v 2.8l and im going to put a custom exhaust on it. Im going to buy a magnaflow muffler #14816 and the inlet of it is 2.25" so is there any point in getting piping larger than that for the exhaust? Or is the 2.25" per tip on the muffler, because its a twin tip muffler. Would my performance increase a little bit with like a 3" piping for the exhaust?
