Just to point out to those that say "Look at that bracket, it's miles out" - the casing in the photo is an early one. Later casings had an extra piece to allow the extra bracket underneath to attach. So there is nothing wrong with the exhaust apart from having a bracket that only attaches to later casings.
So easy to jump to conclusions when you don't know the full story.

Early casing, bracket for late casings. See above.

This issue is covered in just about every manual, explaining that the period fix for early casings was to drill and tap the closes lug that you can see, then cut the bracket off and reweld it in the appropriate position. The 60s tuning manual covers this in greater detail, whereas most other manuals simply refer to the revised mounting after the TV200.
The same applies to early 125/150/175 cases so if you use one of these (converted to 200cc for an Avanti!) then you would be faced with the same issue.

This explains the reason the bracket looks like it has nowhere to go.

Agreed , I put up my pics to show that the exhaust fits on a Avanti kit with minimal fettling needed
Ref the mounting lug - as Adam and yourself says, there is an additional boss on later casings so I just drlled and taped the out of position lug , made a extension plate and Roberts your Aunties live in lover

Check for a little hole under the top bracket. Block one end, blow down the other.
Seen three so far with this........Had to remove bracket weld hole and reweld bracket back on......
Think they were all from the latest batch.

Doesn't look particularly tapered reckon it must be something like 48mm.
Mines away for coating hopefully back soon.
