I have a 2010 gmc duramax that's straight piped now and it's starting the have leaks, with the muffler in this kit (as truck is fully deleted) will it be OK with out the def? Is the muffler just to keep it a bit less noisy? That would be nice.
The muffler will keep noise down and clean up thngs for you with a fully removed DPF!
