Motad NETA - advice appreciated

[BristolGSX]

I have a Motad NETA with a bad dose of baffle rattle. Motad don't sell the rear silencers and as the whole system is nearly 400 pounds, I thought if I cut the pipe just where it is welded onto the silencer:

Get a link pipe/mild steel pipe welded onto the cut pipe and a standard end can (perhaps a bit of fabrication on the hanger or a bracket or two) - I may be able to end up with something that looks like this:

My question is - would I need to look at the carburation/jetting if I do go down this route?

Any help/comments will be appreciated - thanks

I would guess probably not but there's only one way to find out!

Have you thought about working out where the baffle is rattling and drilling a small hole followed by screwing in a self tapper to hold the baffle still? If you drill from underneath nobody will see it.

Not likely to need jetting if the only mod you do is change the muffler. As long as there is some back pressure, you should be fine.

Update - thought I would check all the bolts & fastnings before taking a blade to the exhaust.

Appears that the main clamp bolt, where the downpipes feed into the collector/rear silencer, had been grounded. Removed and replaced - tightened everything - no rattle.

Will test this week with the daily commute to see if it is sorted.

Thanks for all the input
