AMS AMS.38.05.0001-2 Downpipe with EPA-verified Ultra High Flow GESI Catalytic Converter for TOYOTA GR Supra B58 3.0L Turbo Engine (USDM models only)

Description AMS AMS.38.05.0001-2 Downpipe with EPA-verified Ultra High Flow GESI Catalytic Converter for TOYOTA GR Supra B58 3.0L Turbo Engine (USDM models only)

The 4.5″ full mandrel bent downpipe offers high performance and durability. Power delivery is improved, with earlier turbo spool-up. The long, gradual transitions in the mandrel bent pipe allow exhaust gases to maintain velocity and reduce back pressure.

The catalyst features a newly formulated substrate designed to meet new vehicle emissions requirements. The downpipe is engineered using CAD for maximum exhaust flow and a precise fit. Heavy gauge 304 stainless steel construction helps retain heat, and the design allows for easy installation with no cutting required.

Product Notes: Does not fit world market vehicles outside of the USDM.
