  1. Forddog –

    Fits good and easy to install i would recommend it

  2. ken98 –

    it was a fairly easy install for me didnt even have to jack up the truck. it all slipped together great. the only issue are the clamps are garbage. all the nuts strip as they get tight. i went out and had to buy new clamps. didnt matter if i used a standard or metric socket. if it wasnt for that it would be a 5 star review.

  3. BernardoR –

    #1. Pipe tips need to be stretched #2. Cutting required #3. System shown can only be installed when spare tire is permanently removed. #4. Packaging doesn’t include a decal for advertising. #5 Has a good tone

    Great product took about 1 1/2 hours to install, when you put it on for about 3 weeks there will be a strong smell of paint burning I assume it is from the muffler, never the less the smell is gone.
