So I have been building my ap1 up for almost two years. Done alot of engine and perfomance mods, done the suspension and wheels then I started on the outside. Of course I started in the front with the lip and from there I really just focused on the front and "forgot about my rear..."

So I have seen a couple rear ad ons but never really found any rear lips. Wondering whats out there... rear lips, ad ons, etc...

So lets see them

 

Search rear diffuser.

J's. Game over.

 

J's diffuser is BY FAR my fav. diffuser. So sick, but the only thing is I run a single exhaust and I would either have to switch to dual or look like I "missed something." Its only my opinion, but I have seen the J's diffuser on an ap1 running single and I didnt like how it looked. Again, thats only my opinion.

But then again almost everything that is fabricated for the rear of an S that I have seen is designed for dual exhaust...
