PRODUCT SALES ARE ON HOLD PENDING EPA COMPLIANCE DECISION ON THE CATS FI EXHAUST USES

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. AMS was able to design a superior product due to their 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.

While we believe this product is either CARB EO exemption applicable, or complies with the EPA's Anti-Tampering Policy, we have not completed the required testing and administrative process at this time. This product is not available to purchase for emissions-controlled vehicles located within the state of California, or available to ship to California addresses, without a completed AMS Race Waiver form. International users outside of the United States should act in accordance with their local laws and regulations.
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. Our 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.
