  1. Graves Velocity Stacks

    Posted by Dave on Oct 14th 2023

    Can’t say enough good things about the installation videos. Tremendous help. Hardest part was getting the glue off that held the stock ones in. Quality workmanship on the Graves stacks .Just waiting on the ECU to return and the high mount exhaust so I can finish up and see how it performs .

  2. Great produce

    They were a quality build and they came on time. Can't wait to use them with a few more add-ons
