( I don't have access to the car at the moment or I would measure myself) also, it looks like the oval shape helps them fit as well, true ? Or can I get more of a box shape in there.

Pretty damn loud. Lol. May put some turndowns on them. Harder to hear my music now. There is a little bit of drone but overall volume at idle probably increased 25% at least and volume at WOT up by a good 40%. It absolutely screams more than the spiral flows did. But I wanted "loud", and I definitely got it. There are times I second guess going WOT in city limits cause I'm afraid of getting pulled over.

I see we've been in some 1 chamber threads together. I had the Spiral Flows for over 6 years. I bought the system second hand. After a few years and starting to read that Spiral Flows flowed badly, I began to wonder. They sounded great and with my PB of 11.41 @ 122 MPH in the 1/4 I began to think that SFs couldn't flow THAT bad if I'm hauling it like that. I was happy with the performance just wanted something a little louder. However, I am very curious about getting back to the track with only a muffler change to see if SFs were restrictive as everyone says.
My advice, pull the trigger and do it ASAP. I procrastinated for well over 2 years. You can only read the same "1 chamber vs XR-1 vs Magnaflow 14119" threads so many times before you just have to push yourself off the fence.

Over Axle True Dual
I just went over axle true duals with mandrel bent piping, x-pipe, and sweet thunder mufflers. All the piping is 2.5 inch. After going over the axle the exhaust is extremely raspy and flappy?! What in the world could cause it to do that? Mufflers? Not sure why it would be flappy.
