new member here, 1st post! just bought myself a 03 XR6T, so far has the injectors done, cai, cappa flash tuner (runnin 12psi), and cat has been gutted... has been dynoed at 278.3rwkw... but in the future am aiming to hit the 300 club goes hard but it needs some sound to it so I need some advice on what exhaust system to get?? should I go a full system or just cat back? also should I replace the gutted cat with a HI-FLOW? cheers
