Boost Power, Cut Restriction – Emissions-Friendly Performance
Upgrade your GR Supra’s performance with our Sport Cat Downpipe, featuring a high-flow 200 CPSI (cells per square inch) catalytic converter. Engineered to reduce backpressure while maintaining emissions compliance, this downpipe is ideal for enthusiasts seeking more power without triggering CELs (Check Engine Lights).
Constructed from high-grade stainless steel, this downpipe delivers noticeable gains in throttle response, turbo spool, and overall horsepower.
Whether paired with a stage 2 tune or used as a standalone bolt-on, this is the performance downpipe your GR Supra deserves.
