Active Autowerke has over 38 years of expertise developing & offering custom BMW performance parts. Speed Industry is proud to be an authorized dealer for a brand with such extensive experience with the BMW and new Supra platform.
The Active Autowerke Supra MKV Signature down pipe utilizes 4.5” diameter stainless steel piping in order to provide more power, quicker spool, and extreme durability. It then tapers down to 3.5" where we've incorporated a stainless flex joint and then down to 80mm to meet the OEM exhaust system. We never drop the diameter to smaller than the stock diameter of 80mm.
