So I am going to go single on the exhaust for performance reasons...but I cannot stand the way an AP2 rear bumper looks with a single exhaust.

Can I do a straight up swap for an AP1 bumper? Will I have to modify anything to get it to fit? I didn't really find an answer to this question on a search.

BTW, probably getting a T1R 70mm headerback.

 

Swap away. It just fits. Nothing needs to be changed. Now you may need to change the hangers on exhaust to get it to fit right.

 

well I have some people telling me a bracket has to be slightly modified and others say its straight bolt on....just want to know ahead so I can just order some extra brackets.

 

you can get an exhaust cap to cover the unused hole.. thats a big benefit to the AP1 rear bumper. Theres a group buy/promotional buy in the sponsors forum for carbon fiber units right now don't know anything about fitment though, sorry.

 

I'm sure you'll be able to find someone willing to swap PLUS give you cash for your bumper.
