Dave - After starting this thread (and having some louder pipes in the shed) I thought it would be daft not to give them a go. :devious
So I've been running with the Staintune shotguns fitted for the past week or so, mainly to run a "noise-acceptability at 6:30am in the morning" test on Mrs Woodward - So far, so good (with the baffles in). :thumbup
The pipes not as shoddy as I remembered, it's polished up well. It's got a much better burble at idle and a bark when you wind on the gas.
Drop me a PM with your e-mail address and I'll send you some pictures.
With the baffles out, it's as loud as a loud thing. I only tried this briefly, see Sprockers thread "Exhaust on loan" - I got the same reaction!
