spoke with TAP, they've seen ICON's suspension set ups for the new titan too. Cant wait to see what aftermarket does to this truck.

Why a filter back exhaust on a Cummins? Turbo back makes sense but the filter back seems counter productive to me.

because epa. don't worry an "off-road use only" system will be out too. along with deletes and what not.
I'm pretty sure Cummins puts the filter up by the engine. A filter back would add another filter unless the Cummins filter is bypassed or deleted. This doesn't make sense to me as by putting the filter close to the engine, the high exhaust temps keep it "clean" without using extra fuel or another inline injection system to generate more heat. Perhaps I am missing something but you aren't going to beat Cummins after treatment for EPA requirements.

Cummins manages to meet and exceed emissions requirements in the toughest markets. After this VW mess, cummins might be the only diesel engine left in North America!

Could be for the non-diesel version?

DPF is only for diesels, gas pots just use the normal cat setup
