I got a 92' EG with a B18C (r) swap. I installed a skunk 2 mega alpha power header last week. Just found this : STAINLESS STEEL EXHAUST DECAT DE CAT PIPE on ebay which claims to improve 10-15 HP "depending on engine"

What are other ways to get more HP?

 

a test pipe, and aftermarket exhaust is a good choice. I would buy an alpha 70mm throttle body and port the opening of the oem type r manifold, some rdx injectors and a walbro 255 fuel pump, skunk2 tuner1 drop in cam and get the car tuned it should make 200+ whp
