Product Options

Wastegate Configuration

    • Recirculated (Pictured Above): Choose this option for improved boost control and reduction of boost creep without the extra noise! Please note the re-entry of the wastegate gases on our O2 housing in comparison to the competition, routing them back in at a 90 degree angle just doesn't make sense!
    • External: Choose this option for the absolute best boost control and elimination of boost creep! Please note this option is intended for off road use only.

Ceramic Coating

Advanced ceramic coating has several key thermal properties that yield improved boost response and reduce under hood temperatures! Available in black only.


This product is intended for off road use only. As sound level and emissions laws vary based on location please consult your local authorities for additional information.
