So i was thinking.. A straight through exhaust on an s2k increases horseys would it be the same on any n/a car?

depending on relative ID , and amount of bends etc - it will generally net top end "power" but lower low and mid range power. If anything , it is altering your power band not giving you any more "power".

Since the F20 is a high revving motor like most performance honda motors , the above would generally apply too.

farrrk u guys are crazy! lol but i cant talk :P , with the power it would be more top end if anything sacrificin ur low end - mid but generally IMO not worth it if ur N/A but seein as u got a 2jz y not turbo it?

Its annoyingly loud, especially when vtec kicks in. Heard straight pipes dont release enough back pressure. been through this straight pipe phase like 3 years ago

Lol im on p plates.. so ima stick with n/a for now then eventually big single turbo it. Engine swaps are pricey plus changing the front breaks and whatever else is better in the TT to a n/a car wont be cheap either lol. I'm just trying to source at something that will improve the stock exhaust throughout the rev range without losing bottom end power..
