    Extra power and improved flow

    You notice the difference in turbo response and airflow. Very good quality and easy to install on my GTP38. Extra power with no issues.

    Fits very well and opens the exhaust up for more flow!

    Must have for EBPV Delete

    Good quality and matched the turbine housing perfectly. I ended up Flameproof painting all the cast iron parts and baking them to protect them. Looks good and no restrictions.

    Great Value

    I installed this outlet on my last truck 2002 F350 (right before it was stolen) and it was great.
    Fast forward 1 year and I installed this on my recent 1999.5 F250, and again, works great.

    Don't muck around trying to install freeze plugs in your old housing these are great and not expensive. set and forget the freeze plugs eventually leak and at times come out.
