AMS Performance Street Downpipe w/ EPA-verified Ultra High Flow GESI Catalytic Converter for Toyota GR Supra MKV A90/A91 2020+

The 4.5-inch full mandrel bent downpipe delivers strong performance and long-term durability. Power comes in faster, and the turbo spools much quicker. The smooth transitions in the mandrel bends keep exhaust velocity high and reduce back pressure inside the system. The design came from focused engineering, not guesswork. The catalyst uses a new substrate and wash built for modern emissions standards. It’s not an off-the-shelf part.

  • Lower back pressure creates more power potential
  • Exhaust gas flows smoothly across the turbine wheel
  • 49-state legal high-flow GESI catalytic converter rated for 800+ horsepower
  • Updated substrate meets new emissions standards
  • Throaty tone at wide open throttle
  • CAD engineered for max flow with precise fit and finish
  • 304 stainless steel 4.5” pipe tapers to 3.5” flex for optimal volume and flow
  • Turbine flange gives a clean transition from the outlet
  • 3.15” (80mm) outlet works with stock or aftermarket catback systems
  • Full bolt-on, no cutting required
  • O2 sensors mount in OEM spots with no jumpers
  • Mandrel bent tubing gives consistent, unrestricted flow

First in Class Durability and Performance

AMS builds everything with engineering at the core. Our team used Solidworks 3D software to map every inlet and outlet to get the best exhaust flow possible. The AMS MKV Supra Downpipe is built from heavy gauge stainless steel that holds heat inside the pipe. That helps the turbo spool faster and keeps performance consistent. AMS 3D printed the downpipe to make sure it fits like it came from the factory. The threaded O2 sensor bungs let you reuse the factory sensors without any adapters. Unlike many other options, our downpipe won’t crack under stress. The AMS engineering team didn’t stop at performance. They made sure it sounds clean and aggressive too. This is a part built to last and built to perform.
