Howdy. 2018 3500HD. It's missing the tip/diffuser on the exhaust pipe. Melted the plastic bumper step. Suggestions on what to put on there? Not interested in doing a replacement pipe at this time. Are the stock ones available separately? Haven't been able to turn one up.

Thanks!

GM doesn't sell pieces of the exhaust pipe without the DPF, but you can get a tail pipe section like Jason posted or a DPF back exhaust kit from several manufacturers. Banks claims theirs lowers exhaust outlet temps over stock, but I have no data of my own to dispute or confirm those claims.

Have you checked with your local junkyard to see if they'll cut one off a wrecked truck?
