I bought a new-to-me Speedmaster yesterday. The stock pipes were replaced with straight-cut pipes that say "Triumph 2202701" stamped on them. They are LOUD. They sound great, real throaty, but I'd be happy if I could get them a bit quieter and still have a deep throaty sound. Anyone familiar with these pipes? Can I get some baffles installed to lower the volume a bit?

I would post a photo, but I don't know how...

Thanks in advance.
