DPF-back options?
Just wanting to see some opinions on a DPF back exhaust modification. I'm not interested (at this time) in doing more than that, and I've seen a few options as far as with muffler and muffler deletes. I have a K&N Blackhawk installed and it sounds amazing, and I'd like to do something that compliments that and sounds good without venturing into the turbo back/downpipe back systems. Any ideas/opinions would be very much appreciated. Cheers.

I use the AFE DPF back pipe and I like it. Removes the hair dryer sound and has a nice 5" open tip. All the factory tips get old to look at all the time. I don't think any of them will give performance gain, just looks and quieter.

I didn't get a very good look at it, but I saw a guy that looked like all he did was cut the tip of stock tailpipe off ( just that Y part) and just put a black bolt or weld tip on it. It looked ok from the distance I saw it at, I imagine he only did that for looks.

[QUOTErtazz17;14145794]What dies the fins in the stock tip do? Only thing I can think of is it pulls in ambient air to cool the exhaust?Sort of a venturi effect.[/QUOTE]

U nailed it. I believe there are also fins inside the pipe a few inches deep from the tip that disturb the air flow to create the turbulence that aids the function of those vents to ensure a good mix of ambient air. All adds to the hair dryer sound under heavy load. It's really loud.
