I'm confused now
I've got one of these:
Invidia N1 Cat back Exhaust suit WRX 01-07 - Pro Speed Racing
To me it looks like there's already a cat on the mid pipe there, my question is whether getting a catless downpipe would be illegal?

Will definitely need a tune after that...
Cat back is just for sound, tbe for power and sound  |
