hi,
well im running blue fin stage 1 and like others on here im pretty its not 300 bhp!
i was wondering if i can go to stage 2 on nothing but a cat back? it says i need a sports cat and filter but a cat with less cells and a panel filter make that much difference?
and it would probably only make around 300bhp like most people make on a normal stage1?
just got me thinking!
max.
