justin303films Posted November 18, 2015 Share Posted November 18, 2015 Anyone have any real experience or proof that a aftermarket uppipe on a 07+ legacy 4th gen. Acually increases performance? I Know that the stock uppipe is catless so is there any difference? Link to comment Share on other sites More sharing options...
xtea Posted November 19, 2015 Share Posted November 19, 2015 Better money spent elsewhere if you are already catless. If you are entirely stock get a stage 1 tune from one of the vendors on here or locally. Link to comment Share on other sites More sharing options...
