Active Autowerke A90 GR Supra 2.0 B46/B48 GESI Downpipe

The Active Autowerke B46/B48 catted downpipe is for the four-cylinder Toyota GR Supra 2.0, introduced in the US for 2021. The factory downpipe on this engine is quite restrictive, and this pipe replaces it with a freer-flowing design and a 4 in GESI G-Sport high output cat. Active Autowerke says no performance tune is needed.

The turbo flange gasket is included and comes installed in the downpipe flange, because some installers were damaging it during fitment.

This variant includes a 4" high flow GESI catalytic converter that will NOT produce a CEL! GESi HO-Series Gen 2 Catalytic Converters are EPA registered and compliant in 49 states and fully OBD2 compliant, perfect for use on 1996 and newer vehicles. Say goodbye to Check Engine Lights and failed emissions tests! NO CEL when using this downpipe GESI EPA registered high flow and fully OBD2 compliant EPA compliant for use on OBD2 vehicles (1996 and newer) except in California

What It Does

Turbos are driven by spent exhaust gas; a restrictive downpipe slows that gas and slows spool. This downpipe uses 3.5 in stainless piping for more power, quicker spool and durability, with a stainless flex joint leading to the ball flare or slip-in pipe that meets the factory exhaust.

TIG-welded 304 stainless steel with a cast stainless upper V-band and a 400 cpsi catalyst substrate. It bolts on with no cutting or welding.

• Active Autowerke sells separate B46 (11-566) and B48 (11-569) versions; confirm your engine code before ordering.
• Active Autowerke fitment applies to US-model cars only.
• Active Autowerke covers the shell and tube ends for 5 years / 50,000 miles and the catalyst core for 2 years / 25,000 miles for the original buyer. Excessive burble (more than stock) voids the warranty because it destroys the catalyst core.
