Sounds like he was pretty disappointed with how quiet is was.
To avoid a possible voided warranty, I had the GM performance axle back upgrade exhaust w/tips (part # 92206992) put on today...When I heard it, I was sick to my stomach that I had paid $1027.86 (labor & tax included) for not much more than fancy tips. The difference in the sound was minimal...the tone was lower, but was un-impressive
. It was not that much different than stock
. At first start up, it sounded a "little" loud, but at idle you couldn't even hear it over the fan noise. I knew I was the first for the dealership to install, so I took it for a drive to see if it was better. Still very disappointing...I had the stereo turned completely off and the a/c turned down and still could not hear the exhaust when I "got on it". I told them I was not at all happy with it and to take it out and put my stock exhaust back on...they agreed. They also furnished me a new Avalanche to drive. I think they knew and agreed it was not good.
And by the way, I was there to get a rattle from the passenger door, top speaker and wind noise/window marking checked out, when they told me they could put my exhaust on as well.
I'm going to do some more research to see what I can do without voiding my warranty. I don't want to risk that, not yet anyway. I also have the cold air intake on order.
