The factory 2-piece downpipe works, but it’s restrictive and not ideal for performance setups. The SPE Motorsport 2-Piece Downpipe was engineered to improve flow, fitment, and durability for both the factory 2015–2019 turbo configuration and SPE’s S300 Emperor kits using the SPE adapter.

Built from mandrel-bent 409 stainless steel, this downpipe features smooth internal transitions to reduce back pressure and lower EGTs while maintaining proper clearances. The precision slip-fit connection provides a clean seal and makes installation simple, whether the cab is on or off.

Each downpipe is designed, tested, and manufactured in-house to ensure consistent quality, durability, and performance. The result is improved turbo response, better efficiency, and a perfect fit every time.
