Catless Downpipes

Take your build to the next level with our catless downpipes, designed for maximum exhaust flow and unrestricted turbo performance. By eliminating the factory catalytic converter, a de-cat downpipe reduces backpressure, improves spool, and delivers the most aggressive exhaust note possible.

Perfect for track use or off-road applications, these downpipes provide significant gains in horsepower and torque. Built from high-quality stainless steel with precision welds and direct-fit design, our catless downpipes ensure durability and optimal performance under extreme conditions.

⚠️ Note: Catless downpipes are intended for racing/off-road use only and may not comply with emissions regulations.
