We Highly Recommend adding these products for best results:

  1. Upgrading your Up-Pipes
  2. Upgrading EBPV Pedestal 
  3. Running a Hydra Programming Chip

EXHAUST BRAKES: We get asked a lot about exhaust brakes and if they work with our turbos. 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.
