Modern Vespa

How I love stupid thieves. Yesterday whilst leaving work I notice something odd about my exhaust. I take a look and the two bracket bolts are sheared right off. Then notice hacksaw marks on my chain. Bloody hell.. Zip tied it to the center stand so it was stable and limped it home. Thank god they didn't get my scoot, but now I have the sheared bolts removed and most likely replace the stock exhaust. Anyone know of a good place to get a use stock pipe ? Secondarily, vespa dealer said he can extract those bolts easly thank god, but should I have the exhausr studs replaced while im at it? They don't appear distressed , and they are tourqued down well ;but im concerned they maybe weakened.

Thanks guys

gah! jerks!

speaking of which, I was unable to chain mine to the bike rack this morning, better go check it!

good luck!
