Product Description

Building a custom header or exhaust manifold for an SR20 starts with a flange that matches the factory port layout precisely, and this laser-cut piece delivers that fitment reliably. At 1/2" thick, it's built to handle the stress of a serious forced induction setup while still working just as well on a naturally aspirated build.

Since it's HRPO mild steel rather than stainless, plan to use a 309L welding rod if you're mating it to 304 stainless tubing - a small detail worth knowing before you start fabricating. Port sizing is dialed in for Schedule 10 or Schedule 40 pipe, making it a solid foundation for a custom SR20 exhaust manifold.
