I want to get a catback system and a header for my rsx-s, and i need to keep the cat for state inspection. What setup would get me the most power without have 100000 decibles

for your car i recommend and evo2 from greddy. they are the best. For the headers, idk.

As long as you keep your catalytic converter and only upgrade the pipes like half an inch you should be OK. As far as the CAI goes go with a K&N kit.

well i can gurantee you every exhaust you find will be under 100000 decibles. The pressure wave from that would probably be able to rip this planet apart and then some.I've always liked comptech parts, quite pricey but very good.

Just adding the header and increasing the Exhaust to a 2 1/2" with a free flow muffler will give you the best performance.Those aftermarket mufflers that everyone seems to enjoy hearing will cause you to loose a little bit of power because they use back pressure to get the trawny sound.And realistically speaking you are only talking about gaining at most 25HP by adding the Header and good Exhaust.Any back pressure in the exhaust system at all defeats the purpose of a larger exhaust and headers.

TRY LOOKING ON LINE at HKS.comGreddy.comSkunk works.com Flowmaster.comI would recommend HKS they have one of the best on the market as for catback systems

Hi!If you do not want a high pitched sound like any other Japanese exhaust system on the market out there, I would go with Magnaflow (I had one on my s2000 and loved the sound). However, If you want a cheap $200 exhaust then I guess just eBay some cheap jap exhaust. It will sound like crap and not last long, however. (And I am telling you this from experience).Feel free to contact me if you have any other questions!Tito @ TR-Performancewww.tr-performance.com

I have a DC-Sports race header and Greddy EVO2 exhaust on mine. Nice deep hum and not loud. My friend drove around without a muffler on his stock S and holy crap that thing is like magnified through a microphone.You can always check out the forums on ClubRSX.comThey have sound clips of what an exhaust with header sound like and pictures. Some even have dynos so you can see how much gain you would get.
