4 Inch Top Gear De-Cat downpipe for your A90 2020+ Toyota Supra.
Back pressure is significantly reduced by eliminating the restrictive catalytic converter in the factory downpipe with our decat which results in faster turbo spool, an increase in power & a more aggressive exhaust note. Our downpipe features a full 4″ stainless steel design as well as a 304 grade stainless steel flange that offers a smooth transition from the turbo to the mid pipes. All Top Gear downpipes are hand crafted from 304-grade stainless steel and include a lifetime warranty.
