        5 2018 LTZ - RIDICULOUS Installation Time: Less than 1 Hour


        I really like the exhaust. It was packaged very well. The installation was very simple. Backing the truck on driveup ramps made it very easy to remove the factory exhaust in one piece. I went with this system over the Borla because of the price. I couldn't see spending almost three hundred dollars more(although I wanted to try the Borla system). I also like the single exhaust. It is loud enough for me without being to loud.

        Awesome sound

        I've had this SLP system on my truck for almost a year now and have had no issues with it sounds amazing under acceleration with no drone at cruising speeds would highly recommend. Install is very simple and fast if you have ramps to back you pickup onto to get the factory exhaust out without cutting it.

      How would this system compare with the Carven progressive system? They appear very similar in design. Being loud is not a large concern for me, but interior drone is. Would one perform better than the other in this area?

      • The SLP 3 in. Single Exhaust System and Carven Exhaust Progressive Series Single Exhaust System will both be low on drone. Both will also offer considerably louder exhaust over OEM.
