So like the topis claims i plan on doing a 2.5 full exhaust. w/ high flow cat. BUT will i pass emissions with a high flow? anybody do it? i know i wont pass with the turbo. least i dont think i will. so i can take that off. but i cant jsut swap in an out a highflow cat and my stock cat on a custom exhaust. or can i? will the cat need to be DOT approved you think?
