I have an 06 Duramax that is all stock right now. I’m looking at a 4” exhaust and down pipe. I know I can put this on myself. As far as an EGR delete... I’m not sure I’m confident enough to do it myself and am still a little unsure as to what all is needed. Would a shop like Danville Performance put on an EGR delete kit for me? I’d like to retain the grid heater, put in new Y-Bridge, new up pipe... what else is there to a good delete kit? Thanks in advance.
