        Loud Enough

        I really like the exhaust. It's not extremely loud, but loud enough for me. It gives it that deep sound, which I like!

        Bang for your buck

        Originally I was looking at borla s type dual exhaust but was running into issues with it not fitting my 2015 silverado. So after much debating I googled a video on the sound of this exhaust on a truck similar to my truck. The sound in the video convinced me to buy it and I am so glad I did. I finally have that deep throaty sound that was missing from stock exhaust. There is a difference in power but I also did a kandn cold air intake prior to this exhaust. The quality is great and install was about an hour. For the price it was worth every penny if you find yourself not wanting to spend a lot of money to get a great exhaust sound.

      I live in a subdivision very close to other houses. Are my neighbors gonna know when I leave for work every morning with this exhaust? lol

      Could you somehow tell me the noise level? Can you hear the exhaust report, let's say while cruising on the highway. I just want this motor to breath a little better.

      • From the reviews on this exhaust, it seems to have a nice deep tone that is not too obnoxious.
