AMS Performance Street Downpipe w- EPA-verified Ultra High Flow GESI Cat - 2020+ TOYOTA SUPRA GR A90 A91 MKV

Power comes in earlier and turbo spool-up is significantly improved. The long gradual transitions within the mandrel bent pipe section allows exhaust gasses to maintain velocity without a buildup of back pressure inside of the system. 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. AMS Engineers 3D printed the downpipe to ensure an OEM level of fitment. AMS' threaded O2 sensor bungs allow the use of factory O2 sensor. AMS 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.
