  • Good product
Style: Base Product
Overal good product. I installed this on a 2015 GMC Denali with the 8 speed and 6.2 It's fit good except to the front peice. I had to dint it in about 1/2 an inch to clear one of the crossmembers 2nd, if you don't tighten the crap out of it, it will try to come apart when you take off hard. 3rd, the sound is perfect. No resonance inside the cab but a nice deep throaty sound when taking off. You can hear it inside the cab while on the highway but not with the radio up a little, to give you an idea. If you have 4 cyclinder mode it changes sound during this and sounds like crap, but this will happen with any exhaust system. Just giving you a heads up ... show more
