Greetings all,
The exhaust note on my G3_with_a_500_engine has become noticeably louder. I like the traditional Brit single exhaust note, but it now sounds like an open pipe.
I assume that it isn't standard, no obvious leaks to the silencer or header / down pipe. If the silencer is designed to be repackable then I can't see an obvious way to open it up.
Down pipe = 1 3/4" outside diameter
Suggestions for a replacement silencer please, I am tight with my money!

At the end of the front pipe is there a washer still there or has it "fallen" out?
You could experiment with that and see if it brings the note down a bit.

Thanks Jackstringer, no washer inside the exit to the front pipe. If I do weld a washer into the front pipe then I'd like to get the sizing "right first time"; a 10% reduction in cross section probably won't make much difference, therefore I'll probably aim for a 20% reduction in cross section.
The puzzle is: why has it suddenly got noisier?

You have the wrong silencer what you have is for a twin. There are lots of single silencers around both new and s/h

That would be about right

Thanks Tony.
To update this, I couldn't find a new silencer in the correct AMC style that was within my budget, and as I try and follow the true path of parsimony, I sssspent £6.70 of my own money on one of those new fangled "dB killers", for insertion into the silencer exit.
Subjectively, it sounds quieter at idle, but still "cracks" at higher rpm. The objective test was encountering two horses (plus riders) earlier today, no adverse reaction from the nags, which makes a change.
