Tail pipes all the way to the bumper. 2.25" all the way from front to back.
I was at a car show today and there was a '63 vet there with Magnaflows. His vet didn't sound anything like my dart. Apparantly big blocks, the dart, need more sound control that small blocks. His was pretty quite at idle compared to mine.
There was also a guy there with a '67 cuda with a 318 with 320hp. Talking to him it sounded like he might of had Dynamax VT on it. I didn't get to hear it run. There seem to be a number of variables that effect how the mufflers sound. It's hard to know how they will sound unless you hear them on the same setup so finding the ones you like can become expensive. I'm hoping my next choice is the last.
