Hi all, I have the D&D Bobcat exhaust on my 2013 Streetbob and on a ride the other day noticed the muffler was almost about to fall off. When i got home and had a better look i noticed the ring bracket holding the muffler had broken at one of the factory welds. I assume this has been like this for a while and the muffler has slowly worked it's way loose until it slipped right back. I've had the bracket re-welded and am going to put it back on, but pretty sure it's going to give way again  as the bracket is bolted to the frame with no movement and assume with the vibration through the exhaust that the stress will fracture it again.

Has anyone else with this exhaust had the same problem and if so how did they fix it? i was thinking of putting a bit of rubber between the bracket and bike frame to see if that allows for a bit of movement. Any feedback is appreciated.

Checked the header pipes Chriso and there is no bracket there so maybe that is the problem. Would you be able to post a photo of the bracket so I can see where it attaches to. 

Yes your right Daggs the bracket does fix to the gear box, my mistake, didn't look close enough.

Plate for pipe bracket to bolt onto attaches underneath by 3 bolts

This is the bracket that bolts to the bottom of the motor

Thanks for the replys and photos guys. I've got that bracket bolted under the motor but nothing connected to the header pipes. Maybe it was never installed. I had a look at their website and can't see a second bracket in their photos. I've bolted the muffler back on and see how long the ring bracket lasts this time.

i've done around the 13000k mark as well, but think it had been broken for a while as the muffler had been moving back slightly over time.
