6.7 DPF DELETE PIPE BACK EXHAUST

[BOBBYCRAWLEY]

I have a 2011 6.7. I have a delete pipe for it sitting in my office.
I ordered a mini maxx race tuner today. When that comes in i am going to install it all at once hopefully. What i am wanting is a dpf back exhaust with no muffler. The ones i see Have holes in the tail pipe or the tip is funky with holes. My question is do those holes do anything negative to the performance or sound of the exhaust? Thanks.

Sound is about the only thing your gonna notice IMO.

No you'll be fine. May take away from the sound a little.

I am leaning towards a 5" dpf back system with either a 6" or 7" tip

Sell the delete pipe and get a 4 or 5 inch down pipe back exhuast. Then you can get any tip you would like. I personally have a 5 inch down pipe back and love the sound.
