DPF back is just bolt on and go. no mods needed

This is what I have. It's for aesthetics only really but it looks 10X better with a nice stainless tip tucked under there. A full exhaust is a whole different ball of wax.

Apparently it's is more then just that, from what Kory willis was putting on line with facts and specs to follow. It actually created the dpf to flow better. He had a pretty good write about it if you ever were to care that much. I thought it was pretty interesting.
