AMS Performance designed the 4.5" full mandrel bent downpipe for Toyota Supra A90 with the best performing and most durable on the market. The power comes in earlier and turbo spool-up is significantly improved using this amazing AMS Downpipe with Ultra High-Flow. It has long gradual transitions within the mandrel bent pipe that allow exhaust gasses to maintain velocity without a buildup of back pressure inside of the system. AMS Downpipe also features a heavy gauge stainless steel to retain as much heat in the downpipe as possible. AMS engineers used 3D printing of the downpipe to ensure an OEM level of fitment. You can also use the factory O2 sensor because our threaded O2 sensor bungs allow it. AMS Engineering Team proudly to say the product they produced doesn't just perform better, they made it sound better too.
