We are proud to announce the AMS Performance Stainless Downpipe for the 2020+ Toyota GR Supra. Power comes in earlier and turbo spool-up is significantly improved. The long gradual transitions within the mandrel bent pipe section allow exhaust gasses to maintain velocity without a buildup of back pressure inside of the system.

The 4.5" full mandrel bent downpipe is the best performing and most durable on the market. Power comes in earlier and turbo spool-up is significantly improved. The long gradual transitions within the mandrel bent pipe allow exhaust gasses to maintain velocity without a buildup of back pressure inside of the system. We were able to design a superior product because of our superior engineering.

AMS is first and foremost an engineering company. The AMS Engineering team utilized Solidworks (3D software) to blueprint the inlet and outlets to optimize exhaust flow. The AMS MKV Supra Downpipe features heavy gauge stainless steel to retain as much heat in the down pipe as possible. Our Engineers 3D printed the downpipe to ensure an OEM level of fitment. Our threaded O2 sensor bungs allow the use of a factory O2 sensor. Our downpipe performs better and are not prone to cracking like the alternatives offered by some of the competition. AMS’ Engineering Team produced a product that doesn’t just perform better, they made it sound better too.
