If you're running the 40mm solexes your engine will be reasonably quiet until 3000rpm, then the induction noise kicks in, it may not be quite so loud with yours.You have a single air box from memory?. The induction noise will be loudest at 3800 and from then on the engine will just scream its self to redline.
We have extractors (approx 1.5" I think) with a 2 inch using a turbo flow-through muffler and a 2.5" tip. It is fairly mild at idle but the flow through muffler makes any missfires pretty obvious. If you have a bad idle, I would suggest going for a smaller exhaust than many guys are running, higher backpressure will override some of the effect of the lumpy cams at idle and it may idle smoother. This will also make it quieter.
Of course, if you go for a small exhaust on a worked engine you'll be losing top end power I reckon, but the bottom end torque shoudlbe much better.
When getting your exhaust, make sure that you have the exhaust linked up with your extractors by way of a flange, this way, once it gets passed (assuming that it will) you have an easier job changing it over to a more effective one. It also make it easier to do work on the engine if you can easilr remove your extractors.
