Replacement for DMC quiet core pipe

I have a 2009 YFZ450R. Back in 2011 (after purchasing the machine as a new leftover), I installed a power kit from TQSATV.com that included a DMC Quiet Exhaust and header, MSD blaster, and new airbox filter. It has been a great system but last fall the mount ripped off of the pipe.

DMC has been giving me the runaround since October about a replacement pipe (part number ZZ-25465-04) indicating that they are out of stock and it's always 6 week out. This has been going on for 5 months so I'm now considering alternatives. I do need something quiet enough to pass inspection in WI and MI (silver lake dunes) and I'd rather not have to mess with reprogramming the MSD. Any suggestions?

What part broke. I used to have a dmc comp 4 full on my z400 and no issues. Suks only one mount.

2018 YFZ450R SE : warning labels removed, TMD case saver, GYTR aluminum frame skid with the bracket mod, thick helicopter tape here and there, some stickers, everything else stock stock stock like the dealer likes it.
PIN IT PIN IT !!! SCREW BREAK IN STEPS.

The mount on the can ripped out of the can itself. Can't be fixed - so all I need is the can.

The metal on the can isn't thick enough for a weld to hold.

If the can itself is good if it was me I would take it apart and drill some holes and bolt it up somehow to the existing bracket. Assuming can itself is still good. Use the broken bracket as a guide if possible to secure the pipe to your custom bracket.
