Cool. Thanks for the demensions. It sounds like the round 6x6" 27" XL variation. The 13746 is the round 7x7" 27" XL variation. I Just ordered it and going to have it installed this week. I'll post a sound clip for comparison once installed. Probably Going to delete one of the cats. We will see how it comes out.
Thanks!
 
Maybe the 7"x7" 13746 will be a little quieter for me?
It looks like yours is the MF XL PART#: 13646

Looks good! How's it run and sound?

And that underbody is WAY to nice!

I love it. Perfect for my DD needs. Not too loud with a refined mellow rumble. I'll post a sound clip when I have a chance to upload to YouTube.
Price:
It was 100 for the muffler, and 200 for the labor. Which included removal of one resonator down to one (aftermarket 3way resonators from PO), fabricating a whole new pipe in order to re-route over the frame, cutting out/welding/relocating O2 sensor, and the muffler swap out. I watched him do the whole job. The rerouting is not novice exhaust work.
Thanks for the undercarriage complement. I'm really big on preventative maintenance. I plan on keeping this baby 4Life.
 
I also just replaced the filter with a K&N drop in. It seems to breath a little better all together now since the cat delete and muffler upgrade. Love the sound at WOT but sounds very close to stock at idle.
I did a lot of research in regards to over the frame rerouting and saw the conversations about the 3FE OEM heat shield. I opted for this Thermo tech heatshield adhesive since I could not procure the stock part from my local dealer and did not have time for a local Pick n pull run. Also did not want to pay the $114 for it.
