i am not to familiar with dpf systems but i think it would not do a thing to help it breath better ?

Don't waste your time with it. The dpf is so restrictive that your truck will be just as quiet and choked up.

Yes you can, it wont cause any problems, although like Bag711 it wont do much, I have my truck as a full straight pipe from the turbo back and its really not that loud. Also note that when your truck goes into regen your exhaust temps get really hot, and the stock tip helps cool the gasses so you don't light things on fire, so if you remove that as well be careful what you park next to.

with the three guys above me. It does absolutly nothing for sound/performance. It's cosmetic only.

Ok, thanks everyone for all the info.

Think about t like this... You are exhaling thru 2 straws stuck end to end. Now replace the second straw with a funnel. It won't make it any easier to breathe. It's gotta be the whole system to really make a difference.

it's more like you're blowing through three straws and a funnel... and you're talking about replacing that funnel with a bigger funnel

the factory dpf-back is barely more restrictive than a 4" straight dpf-back... it has essentially zero restriction when compared to how restrictive the dpf is
