So I am very interested in going single exhaust (T1R 70mm) for perfomance reasons but I have an '05 and there is not yet a cap for the empty slot.

I am considering an AP1 rear bumper conversion with the cap mod for looks. My question is, how much modification does an AP1 rear need to fit on a AP2 ('05 specifically)? Anyone know?

 

From what i've seen... and heard you need nothing at all. Maybe you have to bend the bracket and tahts about it.
