Active Autowerke Toyota Supra B46 Catless 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 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.

Active Autowerke B46 Downpipe Benefits
The speed of a turbo's impeller wheel is limited by exhaust back pressure. A larger down pipe relieves some of this pressure, resulting in quicker and more efficient spool. With Active Autowerkeu's downpipe, your B46 can rev quicker, and deliver more horsepower and torque.
Minimizing back pressure while retaining daily drive-ability was the goal of our B46 downpipe. Owners can now upgrade to a product that is affordable, reliable, and easy to install.
After months of research and development, our engineers settled on a 3-1/2 inch diameter pipe which utilizes the least number of bends possible. The large volume helps the turbo spool as quickly as possible by eliminating back pressure during spool up. We are ushering in a new era in performance where we maintain air control standards without significant losses in power by using the GESI super high output catalytic converter in our signature downpipe.
Constructed entirely from 304 stainless steel with 1.5MM wall thickness, we are confident that youu'll be pleased with how robust and durable this down pipe is. Trouble-free installation and a long lifespan ensure that you'll enjoy many miles of performance with your B46!
