A buddy just sent a video he did a full muffler and DEF delete on his 2015 sierra 2500 dmax, it has 2k miles on it he drove the piss out of it for about 300 today doing burnouts and such and it hasn't thrown any codes yet..????
He's going to tune it but he has money like no tomorrow and this is his sema truck so it will be sold after it ya built but my question is isn't that bad on the truck to be driving like that? Not that he cares but I just thought what in the hell is he thinking..
