Is it worth getting a muffler with no exhaust? Will it change the sound? For the better?

 

It would definitely change the sound and for the better. Not sure how loud the 6 would be with a different muffler. I'm running a "muffler delete" on my 1.8t right now and the mid-muffler does alot of sound dampening.

 

Well it doesn't sound bad completely stock, so I bet it would be a bit deeper?
