The goal with any performance header design, is to get exhaust gases to flow out of the engine faster and more efficiently, which in turn will produce more power and performance. The K-Tuned RSX Header was designed with this exact theory in mind and utilizes a proven 4-2-1 Tri-Y design with extremely smooth slip fit merge transitions to increase the exhaust flow and power output of the Honda K engine. Like most Tri-Y designs, power gains are seen almost everywhere in the power band, not just the top end. Fitment is equally if not more important to us than function and although the subrame and swaybar on the RSX presented some design challanges, the final fitment was definitely worth some extra time. The secondary tubing passes perfectly through this tight area with extra clearance for engine movement.

The header features stepped piping beginning with 44mm primaries that progressively move into 48mm, then 50mm secondaries and finally a 64mm or 2.5" exit. Like all our stainless headers, it is assembled with mandrel bent, 304 stainless steel tubing and is fully tig welded. We also use a slightly thicker gauge tubing that allows for better weld penetra
