Active Autowerke Catted Downpipe – 2020+ Toyota GR Supra A91 2.0 (B46 Engine)

The Active Autowerke Catted Downpipe for the 2020+ Toyota GR Supra A91 2.0 (B46 engine) is engineered to dramatically improve exhaust flow and turbocharger response while maintaining excellent drivability. The factory B46 downpipe is restrictive, creating unnecessary backpressure and limiting the potential of even a lightly tuned Supra. Active Autowerke solves this with a high-flow, stainless-steel catted design that enhances throttle response, reduces turbo lag, and helps the engine make more efficient power.

Each downpipe features precisely TIG-welded stainless construction, a high-flow catalytic converter, and CNC-machined flanges for perfect alignment with factory turbo and exhaust components. The result is a deeper, more refined exhaust tone and a noticeable improvement in midrange torque and turbo spool.

Designed for enthusiasts who want performance without harshness or drone, this downpipe maintains excellent drivability and is compatible with stock or aftermarket exhaust systems. It’s a premium bolt-on solution that elevates the performance of the A91 2.0 platform without compromising reliability.

Note: May take up to 2–3 weeks for production.
