Street Downpipe with Catalytic Converter
2020+ Toyota GR Supra
The top-performing and highly durable downpipe on the market is the 4.5″ full mandrel bent version. It brings power in earlier and greatly enhances turbo spool-up. The mandrel bent pipe’s extended and smooth transitions enable exhaust gases to maintain velocity, preventing any accumulation of back pressure in the system. AMS has developed an exceptional product thanks to our superior engineering expertise. Additionally, the catalyst in this downpipe features a specially formulated substrate with a specific wash to meet the latest emissions standards for new vehicles. It is not a generic catalytic converter found off the shelf.
