Show original supplier description
The MAPerformance Catted Downpipe is engineered to enhance the performance of your 2020-2021 Toyota Supra 3.0L A90. It features a direct-fit design with a 4.5-inch 304 stainless steel construction that smoothly transitions to the factory connection point. At its core is a high-flowing GESI catalytic converter, capable of handling up to 800 horsepower and meeting 49-state emissions requirements. The use of 304 stainless steel provides superior corrosion resistance and durability, while a stainless steel flex section reduces stress from engine movement, increasing longevity. The CNC-machined turbo outlet flange ensures a proper seal and optimal exhaust flow from the turbocharger. The downpipe retains the OEM O2 sensor locations, requiring no additional wiring harnesses or jumpers. Benefits include significantly lower back pressure, improved turbo spool-up, and a throatier exhaust note under wide-open throttle. The unit is handmade in the USA and comes with MAPerformance's Limited Lifetime Warranty.
