Best exhaust for the 6.7
 

What is the best sounding exhaust for the 6.7 cummins? Wanting to go with a 5 inch exhaust, but do not know which one to buy.

There all going to sound the same if you straight pipe it. The only difference is going to be the design of the muffler. We have a lot of happy customers running our Expandit or FloPro Kits.

the flo pro installs easy and fits good. go straight exh for sure

I love how flopro sounds get people asking about it all the time

Anyone ever just put a 90 degree bend off the back of the dpf, or whatever it is that's in the end of the line before the muffler and dump it out the side? I'm thinking about taking this route... at least until someday when the emmissions stuff falls off the truck.

I don't expect any power from it, but if it sounds a little louder, I'm good with that.

It won't get you much if any performance

i tried that and 100 later it still sounded the same so i wouldn't go that route the dpf is the prob on any sound

Good to know... I'll leave it alone until it's all gonna fall off.
