The Active Autowerke B58 A90/A91 Downpipe with GESI G-Sport Catalytic Converter is designed specifically for the BMW-sourced B58 engine found in the Toyota Supra MKV. Replacing the restrictive OEM downpipe, this upgrade improves exhaust flow and turbo spool through its large 4.5" stainless steel piping, tapering smoothly to OEM exhaust size at 80mm without dropping below stock diameter.
- Includes a 4.5" high flow GESI catalytic converter that prevents CEL (Check Engine Light)
- Constructed from TIG welded 304 stainless steel with a casted upper stainless V-Band for precise fitment
- GESI G-Sport Ultra High Output catalytic converter is EPA registered, OBD2 compliant for 1996+ vehicles (not CARB compliant for California)
- Catalytic converter rated for 500 to 850 horsepower applications with ultra-high flow 400 cells per square inch substrate
- Durable construction withstands temperatures up to 1500°F and reaches efficiency within 9 seconds of startup

- Backed by a 5 year/50,000 mile warranty on shell and tube ends, and 2 year/25,000 mile warranty on the catalytic core
This downpipe addresses the factory B58€™s restrictive exhaust that slows turbo spool by providing a more efficient path for exhaust gases, enabling improved performance potential when paired with signature exhaust systems. Note this catalytic converter meets EPA standards but is not legal for California emissions.
