AMS Street Downpipe w/EPA-Verified Ultra High Flow GESI Catalytic Converter - A90 Supra
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.
Ultra High Performance
The AMS MKV Supra Street Downpipe features a catalytic converter that is a brand new design and application specific. It features a newly formulated substrate with a specific wash for new vehicle emissions requirements. It is not an "off the shelf" GESI unit.
Performance From Proper 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 factory O2 sensor. Our downpipe 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.
