AMS Street Downpipe For MKV A90 Toyota Supra

With 20 years of documented research and development in the forced induction field, AMS Performance has proven itself as the powerhouse in the automotive aftermarket. Our award winning performance systems are what all others are measured by. Be the Alpha.

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 allows 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. The catalyst has a newly formulated substrate with a specific wash for new vehicle emissions requirements. It is not an off the shelf cat.

First in Class Durability and Performance 

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 factory O2 sensor. Our downpipes perform 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.
