Active Autowerke Toyota Supra B46 Catted Downpipe

BMW introduced a new valve-tronic, single turbo version of its direct-injection engine for the later F-Chassis models beginning in 2016 and continuing into the G-chassis models. This proven 4 cylinder engine has now been introduced into the Supra MKV in the 2021 A91 2.0. The Active Autowerke B46 downpipe for the Supra A91 2.0 helps unleash some of the potential that is restricted by the OEM downpipe.

Turbochargers are powered by spent exhaust gases created during the combustion process. The quicker these gases are evacuated, the better. Unfortunately, the factory down pipe in the B46 is quite restrictive, which results in slower exhaust gases and slower turbo spool.

The Active Autowerke F-Chassis B46 Signature down pipe utilizes 3-1/2 inch diameter stainless steel piping in order to provide more power, quicker spool, and extreme durability. We've incorporated a stainless flex joint and then to the ball flare to meet the OEM exhaust system.

This variant includes a 4" high flow GESI catalytic converter that will NOT produce a CEL!

The GESi G-Sport High Output Catalytic Converter features full 304 stainless steel construction, including the substrate. 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. GESi proprietary precious metal loading technology ensures greatly reduced emissions, eliminating most "Check Engine Lights". These high flow catalytic converters outperform stock converters and provide a reliable solution to the most common catalytic converter problems.

The GESi HO-Series Catalytic Converters are rated for engines putting out between 300 and 500 horsepower while maintaining a high flow capacity. The reduced back-pressure from this high flow catalytic converter will allow you to maximize your engines horsepower without the harmful emissions. Say goodbye to Check Engine Lights and failed emissions tests!
