They won't fit. I know from experience. One is BSP. Not sure which one though.

 

Any body got one of these installed in the Chicagoland area?

 

I'm in Springfield (about 3 hours south of Chicago). I'll be up in Chicago at AMS on the 21st to get tuned though. If you want to stop by to check it out, shoot me a PM.

quick question that ive had after reading this thread and looking around the internet - is it inefficent to retain the dual exhaust of the s2000 even with aftermarket cats and muffler and piping - basically, say i wanted to put the 3" inlet apex'i N1 exhaust on my s2000 after a turbo kit - would i get better performance with just one outlet or would it hurt to have the dual with dual mufflers?

 

Depends on the turbo/wastegate. If your turbo/wastegate can handle the flow, the free"er" the better.

 

Just watch out for boost creap... best to use a small dual piping and TP or cat with single.

 

u think 2.5 with some high flow cats or test pipes on a dual setup would be good?

 

I have a 2.5" dual setup with hiflow cat and my boost holds consistently between 9.5 - 10. It was tuned at 10psi. This is using an electronic boost controller that is turned up to hold that boost. I can lower it in the winter to stay under 10.

 

I'm new to s2ki.com, but have been reading posts for quite some time now. I know Mikemjohnson has already touched on this subject, but am wondering what would be best. I also don't have a boost controller right now. Only A/F and boost. I have a greddy turbo kit on my car right now and all I have is a megan test-pipe. I recently bought some N1 turbo mufflers and was trying to decide if I should run 3" back or just leave it at the stock piping. Sorry if someone has already answered this, but I want to make my car perform the best it can.. thanks
