Toyota Supra GR A90 4.5″ J29 Race Catless Dump/Downpipe

Unlock serious performance from your Toyota GR Supra A90 with this 4.5″ J29 Race Catless Dump / Downpipe. By removing the factory restrictive catalytic converter, exhaust back pressure is significantly reduced, allowing the turbocharger to spool faster and deliver noticeable horsepower and throttle response improvements.

Constructed from 304 stainless steel using precision TIG-welded fabrication and CNC-machined flanges, this downpipe is built for strength, durability, and optimal exhaust flow. Designed as a direct bolt-on replacement, it integrates seamlessly with the factory exhaust system as well as aftermarket cat-back systems designed to suit the standard downpipe location.

Engineered to suit both RHD and LHD vehicles with no modification required, this is one of the most effective bang-for-buck upgrades available for the A90 Supra.
