4-2-1 Stainless Steel Header

The 1320 Performance header is engineered for performance enthusiasts looking to maximize their engine's potential. Crafted from thick T-304 Stainless Steel, this header features mandrel-bent tubing and Tig welds for superior durability and longevity. The 4-2-1, 2-piece design is optimized to allow exhaust gases to flow more efficiently, directly contributing to gains in power and overall performance. Specifically designed as a direct bolt-on component for the 1997-2001 Honda Prelude SH model, this header integrates seamlessly with the 2-inch OEM catalytic converter. The brushed finish adds a clean aesthetic. It also fits pre-1965 classic vehicles that have had an H22A4 engine swapped in. Installation requires attention to the motor mount bracket. If aftermarket solid motor mounts are not installed, do not connect the 2-bolt bracket on the down-pipe to the engine block. Doing so with OEM motor mounts may lead to weld breakage due to excessive engine movement.
