All of our Exhaust Manifolds are entirely stainless steel (including ALL flanges), back purged, and TIG welded by hand in North America. Careful consideration for runner length, collector design / orientation, wastegate placement, and turbine flow characteristics ensure optimal performance.
New for 2021, Our redesigned top-mount Manifold now features a Hypetune investment Cast swept Collector with improved Wastegate flow.
Our SR20 manifold line is the result of 10 years of experience with this classic 4 cylinder. These manifold options allow for adaption to your turbocharger and wastegate of choice, and can be built with a merge collector for single volute turbines, or a divided collector orientation and dual wastegates for twin scroll turbines.
Specific to the SR20 application is an unequal length design, that has been specifically designed to replicate the unique and raspy exhaust sound made famous by the Greddy mid-mount manifold kit.
Adding further depth to our SR20 line, we are pleased to offer the Artec Performance| Investment Cast 347 Stainless SR20 V-Band Top Mount Exhaust Manifold.
This SR20 top mount design from Artec Performance features a configurable V-Band flange mounting system and is designed to accommodate a 45mm external wastegate.
