The K-Tuned RSX Header was designed to get exhaust gases to flow out of the engine faster and more efficiently, which in turn will produce more power and performance. 

  • Fits RSX with K20 engine ONLY
  • 4-2-1 Tri-Y Design with extremely smooth slip fit merge transitions to increase the exhaust flow.
  • Like most Tri-Y designs, power gains are seen almost everywhere in the power band, not just the top end.
  • 304 Stainles Steel and CNC cut 3/8" thick SS Flanges
  • Polished for that show look to stand out!
  • The header features stepped piping beginning with 44mm primaries that progressively move into 48mm, then 50mm secondaries and finally a 64mm or 2.5" Outlet
  • Our 304 Stainles Steel RSX Race Header is assembled with mandrel bent, 304 Stainles Steel tubing and is fully tig welded.
  • This header directly replaces the OEM 2 piece design and eliminates the catalytic converter so we included a short 2.5" test-pipe with defouler for the secondary O2 sensor.
  • The secondary tubing passes perfectly through the sway bar area with extra clearance for engine movement.

Glorious sound
Anthony Sigurani | August 1st, 2020
Pair this header with the k tuned exhaust and it sounds glorious. Literally sounds like a banshee screaming at wot. Definitely worth the money!
Best choice
Nicolas | July 26th, 2020
I have this header for a year already and I haven’t have any problems with it, ni leaks, no cracks nothing,just gains and a really nice sound paired with a nice car back , people talks about this header sounding like crap but isn’t like that, I had and hks turbo cst back and the sound was really nice deep with pops, without tune but the drone still there when the rpms drop,so I got a full 3 inch straight pipe with a Ktuned 3” turndown and I hands down the beat set up and sound a lot of people complement the sound and always ask if I’m tuned, which I’m not loñ
Great product/bad spring bolts
Nik M | June 11th, 2019
The guy above me isnt lying about the spring bolts. they are so damn short i dont see how they just let this go out like this. Besides that great product and everything else fits perfectly.
Great as always. K-Tuned
Vincent DelCiappo | May 13th, 2017
Header fit just as it was designed. Great sound and power gain is noticeable. Love it and very pleased. Good job K-Tuned for making this header fit so well in a RSX Type-S. Only con is the spring bolts that were given to me were a joke. So I got some OEM Honda ones and no issue at all.
