A straight back single 3" exhaust is usually good to around 700whp. Anything above that and go with a 4" as most of the 1000+ whp supras use.
Dual exhaust if you have dual headers single exhaust if you only have one header, as the s2k does.
Our dual exhaust, IMO, was designed for aesthetics not performance.

wow, thanks for the answer guys! Okay I most likely going to get flamed for this but, I'm about to pick up a megan racing exhaust ... i'm hoping the sound would be a little, or actually MUCH quieter than lets say .. and invidia v3? my friend is running a testpipe on a invidia v3 and its loud as F#@k

lets just say the megan isn't MUCH quieter than a fighter jet. The megan is a pretty loud one and i speak from experience as i'm running one right now with a test pipe. I do like th sound though, once you hit vtec its music to my ears. imho I don't think anyone should be flamed for buying this exhaust, to each his own right? besides for the amount of money you save you can go out and buy an intake to go along with it.

hks = power loss?

nearwater4me

That's a question, right?

No, I've done tons of search on this forum, and no one who thinks that HKS loses power have proof.
Show me a single dyno chart and I'll admit.
But still, I enjoy my HKS so much that even after I DO see a proof, I won't trade it back.

Best bet would be to watch the for sale section of the forums actually. If you don't mind used.
