Toyota Supra GR A90 MK5 AMS Performance Stainless Steel 4.5" Downpipes

Our Engineers 3D printed the downpipes 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.

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 section 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.
