We have found that some brands have clearance issues and might cause the brake to hinder performance, rub the turbine wheel, or cause other issues. These brakes typically use some sort of flapper to close which causes extreme exhaust back pressure to aide in braking. This can be hard on a turbo and motor and is not recommended. It will be up to the customer to verify fitment and functionality.** **We Highly Recommend adding these products for best results:** Upgrading you up-pipes Upgrading EBPV Pedestal Running a Hydra Programming Chip.
