Overview

The K-Tuned KRH-RSX-K24 is a race header designed for enhanced exhaust flow. It features a 4-2-1 Tri-Y design, constructed from 409 Series Steel. The header includes a CNC-cut 3/8" thick stainless steel flange and a 2.5" outlet.

Show original supplier description

The K-Tuned Race Header is engineered as a high-performance exhaust manifold for the 2002-2006 Acura RSX models. This component utilizes a proven 4-2-1 Tri-Y design, known for providing power gains across the entire power band, not just at the top end. Specifically designed for K24 engine swaps in the RSX, this header is intended for use with a Type-S exhaust system and comes with a welded-in converter. K-Tuned emphasizes both function and fitment, noting that considerable effort was made to ensure proper integration despite potential challenges like the RSX's subframe and swaybar. Please be advised that K-Tuned is currently not shipping exhausts or headers. Orders placed for this item will be subject to a 5% processing fee for cancellation and refund.
