Duramax Exhaust Question

Duramax Exhaust Question
My Bro has a 2008 GMC Sierra 2500. He bent the exhaust pipe by backing into a car, and it pushed in the exhaust. Where it is bent to go over the axle, I think it is bent there because it does not stick out as far as it did. It also bent the rear-most hanger. The rubber hanger will not even reach the steel hanger from the frame.
My question is can he just go to a muffler shop and replace the section from just behind the muffler to the end of the exhaust pipe, or does he need to go to GM to get the OEM replacement? It shouldn't effect the warranty but he is in Canada.
Thanks!

That actually is true because it is used for scavenging the heat out of the pipe during regen. RTToys just went through the DMAX school on the new DPF systems and they showed 1100* pre and post turbo during regen. There was enough heat coming out of the tail pipe to light a stick on fire. The scavenging tip must be on there to extract the heat.
