Stainless Steel!
More info:
Claims are +6HP/+14TQ around 2500rpm, the gains are maintained at about +3HP/+4TQ up to redline from there. Bolt-on installation is stated to take the average person 45 minutes (2 bolts and 2 rubber hangers, IIRC). System is all-stainless construction and weighs 6lbs compared to 20lbs of stock muffler! Tone is increased, but not "droney" in the cabin. A shade louder than stock but not too much, if that makes any sense.
Shipping will be from the manufacturer to you, when they are released to the public. (3-4 weeks)
Also, all PMs and Emails returned.
