AMS Performance Street Downpipe with GESI catalytic converter for the 2020+ Toyota GR Supra A90. Long, gradual mandrel-bent transitions let exhaust gases keep velocity without building back pressure, so power comes in earlier and turbo spool is significantly improved. The included cat is a new, application-specific GESI unit with a substrate formulated to meet current emissions requirements.
