Not at all actually, it's not any louder than stock except when you start it or unless you get into the gas pedal and I don't hear it at all on the highway.
In mid July the Borla site said coming soon but I had emailed them and was told they were expecting it to be available in early August so I went ahead and ordered it from the GMC accessories site to be shipped direct to my local dealer for install and they received the exhaust the first week of August. Maybe there is a shortage of supply?
I purchased the primered/ready to paint flares from GMC Accessories. I'm not sure what they did to them to prep them but I doubt there was much sanding involved, they were fairly smooth to begin with. They used a tri coat paint ($$) and I think the total to paint all four was about $450.
Has anyone got their hands on the Borla catback exhaust system on the 2020 HD gas yet? It looks like it's backordered thru GMC accessories and the Borla website still has it as "coming soon"? Does it take that long to design an exhaust system or are they just selling out faster than they can make them? ?
Took me about an hour and a half. I did not remove the inner fender flares, I just popped the flares off, changed out the marker lights and popped the new ones on
I took my truck to my local body shop and we matched it with paint chips. I went with a tri coat paint which was a little more pricey but I thought it matched the best
I did mine myself. These are the primered flares which I had painted to match.
I took one of the inner fender liners off as suggested in that video and realized what a pain in the rear it was only to "save the clips" when the new flares come with clips. ?
After that one I just used my nylon trim removal tool and a little muscle and popped them out with the liners in place.
I placed the order at my dealer on Jan 14. I don't know how they placed it or any other details. I checked in early March and was told that there was a gas engine shortage and Chevy was getting the majority of engines for fleet orders so my truck was delayed. Of course in late March the plants shut down and when they came back up I checked back with the dealer and was told it was still at "preliminary" status and in their opinion I should cancel and reorder as a 2021. I explained to him that wasn't an option because I would be giving up a huge incentive and supplier discount and here I sit. Now I'm finding out the color I wanted was canceled for 2021. Ugh.
