Active Autowerke Catless Downpipe – Toyota GR Supra A90/A91 (B58) Signature Series

Unlock maximum performance from your Toyota GR Supra A90/A91 with the Active Autowerke Signature Series Catless Downpipe. Designed for enthusiasts chasing peak power and turbo efficiency, this upgrade removes the restrictive factory catalytic converter to dramatically improve exhaust flow, turbo response, and overall performance.

With a full 4.5-inch stainless steel design, this downpipe allows exhaust gases to evacuate faster, resulting in quicker turbo spool, sharper throttle response, and increased power potential. The result is a more responsive and aggressive Supra that feels significantly more alive under acceleration.
