All of our Exhaust Manifolds are entirely stainless steel (including ALL flanges), back purged, and TIG welded by hand.  Careful consideration for runner length, collector design / orientation, wastegate placement, and turbine flow characteristics ensure optimal performance.

All of our fabricated manifolds now feature a Hypertune 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. This combination of the front runner being exactly twice the length of the rear two runners while maintaining a stock S13 Turbo flange placement allows for easier configuration with most SR20 setups. 

Please note - while the Turbo flange placement is the same as stock, the longer runner design will require modification to the crankcase breather hoses found on the hotside of the SR20 engine. 

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.

Our current lead time is 2-3 weeks.
