AMS GSEI Catted Street Downpipe 2020-2024 Toyota 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 allow 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. The catalyst has a newly formulated substrate with a specific wash for new vehicle emissions requirements. It is not an off-the-shelf cat.
