Exhaust or Delete pipe?

well guys im planning on getting a dpf delete set up soon,

my problem is the truck is still under warentee and if there is a problem i will be putting it back to stock and taking it to the dealership to be repaired

so would the doc/dpf delete pipe be easier to change back to stock, or would i be better off putting a turbo back exhaust on the truck? just wondering from you guys who have installed these things which is easier

also i was told that the muffler looking canister by the rear axle isnt a muffler, just a look a like one, is there any truth to that or is it an acctual muffler?

Thanks, Tyler

I would do a downpipe back exhaust. Leave the stock downpipe alone since you are wanting to keep your warranty alive. Also, running a downpipe back exhaust will keep your stock tailpipe section from getting all sooted up......which could potentially raise an eyebrow or two at the dealership. I think taking everything out together is easier in the long run anyway. You won't have to worry about the delete pipe basically welding itself to the stock tailpipe overtime.

Im in the same position. My thought is to do the whole exhaust because with the delete pipe your gonna have black soot in the tail pipe that could tip off a dealership to investigate further. With the new exhaust on there the soot is on it, not the stock exhaust. Just change it back if warranty work is needed and it will have a clean tip. That's my 2 cents.

I went delete only and will clean the soot before it goes to the dealer now that I've seen this.

I am going with full exhaust.. I am sure the same rules apply to a diesel.. the less joints, the smoother the pipe the better flowing the exhaust is. PLus you will be going form 3.5 to a full 4 or 5 inch exhaust... That is a muffler and again if you remove it, you'll be getting better flowing exhaust... Better performance
