Rushjob,
I fitted the Sil exhaust properly this time, when I got them I just checked that they fitted the pipe and that everything lined up. I've found that the brackets are thinner than the OEM Remus ones so that the the rubber bushes don't get nipped up and the cans slop about a bit. I need to find suitable washers, about 1" internal ID and 2-3mm thick to use as spacers. Did you have this problem?
Incidentally, they sound terriffic with a really deep bass grunt.
Haven't had them out on the road yet though.
