But you can order the aftermarket Borla Catback exhaust when - (if) - you spec your truck. I did, so mine will come away new, from the dealer, with it. I'm just trying to get an idea if anyone else did and if it exasperated the problem or not. Edit: Thanks bgsntth for the above reply!

Also, I've wondered how many of you with problems have the aftermarket Borla exhaust?

Right now on Chevy's website, they are offering what they call a 'Factory Reduction Below MSRP' rebate of $5478.00 when you use the 'Build & Price' tool. (This is on 2016 Suburbans) I wonder if this is tied into the problems they've been having?

There is so much speculation in this thread that it is not really useful to a noob like me. I've read so many theories and 'fixes' that did or didn't work that my head is spinning. As a soon to be new owner (2016 Yukon Denali XL set to be delivered mid-January) all I can hope for is that I won't face the issues presented here. Good luck to those of you facing these problems now and I hope they get resolved or that you get out of ownership without losing your ass. Not very confidence inspiring in GM.
