will this make my truck a little louder

  • This kit should not affect the sound of your truck, it would just change the exhaust tip location and style. This item is also only compatible with Roush part number 421248.

    Not happy with final location

    Everything went on smooth and dandy except the tail pipes look out of place, they hang down about 4 inches from the rear corner panel.

    Great sound

    This takes your rear exit roush exhaust and puts it right behind the right rear tire. Personally I think you get to experience more of the sound than the rear exit.
