Our new stock location generation 2 downpipe has a divorced wastegate design with wastegate divider for low turbulence and maximum flow. It includes a durable stainless metallic substrate high flow spun cat placed as far back as possible to mitigate heat soak. For gen 2 we added a thicker 1/2" 304l stainless turbo flange that's nearly impossible to warp even for high horsepower applications. A reinforced hanger was added to handle the most extreme abuse on and off the car.
- Entirely made from 304l stainless steel (excellent against corrosion)

- 1/2" thick SS turbo flange, no warping, cut on waterjet machine
