The thing I would do is take the rubber and bolt out and order an isolator from an industrial supplier. Here is an example.

Yup, that's basically the Harley part. You can get 'em w/ male/male, like the one shown, female/female, or a half and half. It's really just a spring w/ rubber molded around/through it.

You suck for being right. :-D Both tabs have cracks at the welds. The bottom tab aint so bad yet, only 3/8 inch hairline. The top tab is bad enough that black goo is collecting on top of the head and starting to run down the cylinder but its on the back side of the pipe so I wont know how bad it is until I pull it off and have a look. Hopefully this is something that can be re-welded? I know it will mess up the plating but if its possible its probly much cheaper than a whole new pipe. Plus I have an FMF Burly which you cant even find anymore. Any suggestions fellas? I may just have to spring for that new PC2 setup I've been wanting but I'm trying to resist blowing my whole tax return on the bike. Pockets are on fire! :evil:

GDubb, you could have it TIG welded then polish the weld and spray it with some high temp clear coat.

Sweet... thats what I was hoping to hear. I was thinking if I could get it welded I would have to touch it up with some high temp paint but a clearcoat never even crossed my mind. I think I'll have to try that here soon and post up the details on how it turns out. I'll get some pics too. Just dont expect it real soon... its gonna be a little bit before I get around to it but thanks for the great idea!

PS... thumbs up on the sig Uzi.

Make sure to check your coil tabs also. My broke on Sunday and the coils needs to be grounded to work. The tabs are just as thin as the exhaust brackets. I machined a new U-shaped for the coil to bolt to and drilled two holes in the old tab to mount it too.
