2015 Delete pipe, or full exhaust?

OK, so I am looking to possibly delete soon, I will go with the MM3 lite most likely from what I have read about it. I am looking for longevity and reliability more than lots of power. My main question here is: Do you need to go with a full exhaust system? or are the delete pipes going to be just fine? From my prior experiences with my old 98 and older cummins was that anything over 4 inch was kind of a waste unless you were going well over 500hp.

Also do the delete pipes remove the muffler, or just the DPF and SCR?

Thanks for any and all feedback guys

You don't necessarily need to go with the full exhaust if your tight on cash. It isn't that much more to do the full exhaust depending on brand. Most people usually do because the aftermarket ones are designed to have as little restrictions as possible and usually like to get rid of everything.

The delete pipes will remove everything from under the truck. It will make it a straight pipe truck if you get the delete pipes.

Thanks, that is what I thought but wanted to make sure. the delet pipes are around 250 bucks, where a downpipe back is almost 600 so if I am staying with 4 inch the delete pipes make way more sense

What exhaust were you looking at? Stainless? I'll send you a pm of a couple exhausts that i have that are cheaper then 600.00

Yeah no **** $ 600.00 bucks is high :rofl:;)

I paid way less then $ 600.00 and I bought 5" TBE full exhaust no muffler like just a little over $ 300.00 that was free shipping to my house FedEx :rockon:
