The AMS Performance street downpipe replaces the factory catted downpipe on the B58 GR Supra with a mandrel bent 304 stainless steel pipe and an ultra high flow GESI catalytic converter. The pipe starts at 4.5 in at the turbine flange, steps down to a 3.5 in flex section and exits at 3.15 in (80mm) to accept the stock or an aftermarket cat-back exhaust. Long, gradual transitions keep exhaust velocity up and back pressure down for earlier turbo spool, and the purpose-built GESI cat uses a newly formulated substrate and wash rated for over 800 hp. O2 sensor bungs sit in the OEM locations so no jumpers are needed; a tune is recommended but not required.
