i wouldnt increase the piping imo. unless u plan on going FI then its only gonna make the exhaust louder, which u may want. but it wont give any real power gains for the money. spend the money ud hae to pay to build teh catback and buy and mount highflow cats. that will make more of a differance then the larger cat back.
