Seems like changing some pipes wouldnt really do anything? I have an 02 S2000, and I purchased DC sports 4-2-1 Ceramic 1 piece header, a Berk Technology Delete pipe, and Skunk2 cat back dual exhaust, and really its just very loud. Im not really feeling Power gain.. I paid about $1,100 for all this, really I dont feel anything, it just sounds like an Indy car or somethin.
On some cars, the oem exhaust is tweaked for maximum power, you can replace anything you want, but because the oem deisgn already figured out how to get the most power from the parts, it will be a waste of money. This is very true with the f20 engine.
The only way to get noticable power, is to start upgrading internals.
Because your exhaust system is already on, its going to be hard to sell it to get your money back. Stick it on ebay and put the money towards a supercharger.
