Sorry been a minute since I have had a chance to reply. I went back and they swapped out the Super 50 to a Super 40 and its got a little more noise, but its still pretty quiet. I will be looking at doing some testing covering up the three little mesh things on each tailpipe to see if that changes anything on the truck. will report when I have a chance.
Picked up a new AT4 last week with the 5.3L. just left the muffler shop. They cut the Y-Pipe off behind the the cats and ran true duals to a super 50 two in/two out muffler and then connected to the factory tailpipes. The truck is still very quiet and I am not happy with what I just spent on it with very little sound gains. I called up there and they told me to bring it in tomorrow afternoon and they would swap it out for a super 40 muffler at no charge. My question is, how much do those 3 little mesh things on the tail pipe right before the tips effect the sound and how loud the vehicle is? A
I have a set of the GM headrest with the DVD players in them from a 2013 GMC. I originally got them for my 2013 before I traded it in. The guy I got them from said they wouldn't work in his 2014 and that is why he was selling them. Well I traded in my 2013 and was going to sell them. I was at the dealership the other day and talking to the guy I deal with in the service Dept and he said that they should still work in my 2016. Can anyone confirm this for me?
I just put a 2" supreme suspension leveling kit on my truck. Its the kit that goes on the bottom of the strut. After everything has settled, it still nose dives in the front a little bit. Is it safe to put a half inch leveling kit spacer on the top of the strut to get a full 2.5" of lift in the front? Or should I ditch this kit completely and get a kit that is a 2.5" leveling kit?
I had a 2010 GMC Sierra with the 5.3 that I put some direct replacement headers on. When I traded in for my 2013 I pulled them off and replaced the manifolds and they have been sitting in the garage ever since. I picked up a 2016 GMC Sierra All Terrain the other day and was curious if these will bolt up in place of my stock exhaust manifolds, or if they would have to be modified to fit.
