Hi! I own 2-2nd Gen Acura CL-S vehicles, a 2001 and now, a 2003 w/manual. My wife thoroughly enjoys her car. It's stock, save for K&N panel filter, CT headers and front springs (one of the rear springs broke, so I put the stock ones back in), 19" Enkei Rajin's and stereo upgrades.
I recently acquired the '03 car and desire to improve its performance. The car is currently stock. I mean, it's not been touched! CT no longer supports this car and it seems no one produces a quality header for the manual CL-S. Aside from springs, sway bars and ridiculously priced CAI's, I've been striking out. Bummer!

Hi there, XS power/SSautochrome sells a set of headers for the 6 speed! I will be picking them up in the new year. I will post links to some before and after videos once I install them

make your own 4" diameter cold air intake.
you are correct, the 2.5" diameter cold air intakes are a waste of money with NO power to be had....
DIY 4" intake... a 45 bend, a 90 bend, some couplers, some clamps.

focus on freeing up the intake path and exhaust path.
but really tho, if you are not able to tune (which i dont think these cars can be tuned) then it's probably not worth modding...as when you free up the intake and exhaust paths, you'll start to lean out in the upper RPMs

I looked on Ebay for my CAI. I found an AEM CAI but for an auto. The only difference is the length of the tube coming off the throttle body. The Automatic is shorter. I went and purchased a rubber tube the right size and works great. Also, I have had XS headers for about 10 years and like them.
