Glass Pipe mufflers on a diesel?

It will be tough to get anyone to help you on this one, newer diesel vehicles have DPF (diesel particulate filter) on them, removal of them is illegal at a minimum. They also have a catalyst. Finally, I don't know that they make a glass pack muffler in a 4" inlet/outlet application.

This will turn on the check engine light and affect the diesel emission warranty due to modification. Unfortunately, we can not modify much on a vehicle anymore.
