If you guys were trying to contact Fullsac during the Thanksgiving holiday, the owner was out of town and then required a few days recovery after getting his marbles rattled in a rollover accident in an off road race car. He's back to work now, try him again.
Steve at Fullsac will either recore yours, or sell you used recored slip-on mufflers, your choice. I have some that I bid on Ebay and love them. Great sound (not real loud) and better performance. Good luck. Hope he is OK.
