Gordon, wondering if this is the thread you were referring to. Non the less, thank you for the drawing which likely jogged Jimmy’s memory.
JimmyT, many thanks for bringing up this thread. For me, it goes straight to the heart of the matter as to what a “sports muffler” likely was in earlier days. No droning, not too loud, and quick response…….this is the best alternative yet that I have come across.
Cheers,

OK, back to the 2.2 in Post #1. Is the ugly gold colour of the Webers standard issue or have they been painted/plated in some previous life?

Well i purchased a brand new pair of IDA Webers about 25 years ago and they certainly were not gold more a mottled light brown

Update on the Webers-yes, tried paint remover in an inconspicuous spot and it does come off. I now have to find a removal method that safely gets into all the nooks and crannies. Bead blasting? and suggestions?

Update on Muffler- Got one now with dual pipes but I don't think that it has not been modded per Trackrash's drawing. I think that it's best that I first test it and check for droning and loudness.

Cheers.

Carb cleaner might dissolve the coating. If it does, once it's softened a large ultrasonic bath will likely free off all the bits in nooks and crannies.

Make sure you don't bathe them in anything caustic. I think Wayne had an issue doing that.
