V3 3" Catless Downpipe

The Whoosh V3 performance downpipe is constructed from durable 304 stainless steel and features a full 3" diameter from the turbo flange to the exhaust connection. The V3 iteration, effective February 5, 2020, incorporates an upgraded flex section designed to mimic OEM flex components, simplifying exhaust installation and better absorbing engine movement during hard launches and shifting. A 2-bolt support bracket is included to mitigate stress on the turbo flange area, and all necessary attachment hardware and a gasket are provided. For 3" exhausts from brands like cp-e, Injen, or Thermal R&D, the supplied 3" gasket and bolts are sufficient. It can also accommodate 2.75" exhausts such as Tsudo. For 2.5" systems, including stock exhausts, a "ring" adapter with a 2.5" inner diameter is used for proper sealing, followed by the gasket and supplied hardware. An optional defouler can be added, and an adapter kit is necessary for mating the 3" downpipe flange to exhaust systems smaller than 3", including stock or 2.5" setups. Designed for high performance, this downpipe is capable of flowing well over 400 wheel horsepower and serves as a significant upgrade for stock, hybrid, and big turbo kits, provided they retain the factory downpipe flange fitment. It is intended for closed course competition use only and is not for street use, as its installation or use may violate the Federal Clean Air Act. Free shipping is included within the CONUS USA.
