If you're going to replace them, consider these: https://www.armoursltd.co.uk/product/silencer-moto-guzzi-t3-s3/
Kind of an old thread but still worth continuing the conversation.
I just last month took advantage of the exchange rate and bought these. The fitment is a little wonky and they're maybe a little too quiet. Their email is funny too- I kept getting undeliverable messages so had to bite the bullet and pay $50 for a long distance call.
Pictured below are the Armours (3), then stock, then Bub's.
If I could get the Bub's apart I'd repack the baffles. I still think stock mufflers look best but all I hear is valve clatter while riding.
