Superb piece of info. an additional task for me to do too.
The silencer hanger that i bought, uro make, was 2mm thick and couldn't hold the silencer any where near level. it was flexing really bad, meaning the complete exhaust weight would be resting/pressing on the head studs.
I added a 1.5mm backing plate. that's now drying. hoping to fit it tomorrow.
I've made 2 down pipes for one head and the two end plates that bolt onto the silencer. again hoping to complete the tubing on the one side tomorrow.
