Hi I'm new here, lookin to buy an S2000. I came across this silverstone one, it has a weird rear splitter. All I wanna know is can it simply just be taken off or do I have to get a standard one to put in its place? By the way I havnt seen the car in person.

Rear splitter

 

agreed looks kinda weird in my opinion, since it looks like it replaced the center piece on the ap1 bumber you could probaly take it off and replace it with the stock piece. If he has it your in luck if not probaly could get one off the board. Most smaller diffusers dont require alot of work to put so hopefully it wont be vary hard. Not very knowledgebable about this though ,
Good luck

 

if it's removable then just buy a rear bumper exhaust cap

 

It looks like the diffuser bit of it is molded in to the OEM rear. You might have to cut the "teeth" off, and then i'd recommend getting an exhaust cap.
