"Absolutely the best exhaust system I have ever installed!The system was much quieter than I expected when I first started the truck, but the power increase was VERY noticeable. After a couple days, the sound increased to a very deep, very aggressive sounding rumble outside, but stayed quiet inside. Installation was very easy, the only problem was the bolt for the driver side hanger mount was too short. Save some time and buy a 2 1/2 inch x 3/8 bolt BEFORE you start." —Doug F from Midlothian, TX bought a Gibson Exhaust Systems for a 2007 Chevy Avalanche.
