Just to get through a test once a year why not get a bit of thin 1/2" chicken wire and a bit of fibre glass mat and roll it like a swiss roll, stuff it up the pipe until after the test then hook it out with a thin wire coat hanger until next year.

I don't know how much help this will be, but it lists some similar pipes from V&H, along with ways to quiet them further if you happen to not pass.  http://www.gadgetjq.com/vhbagger_shhh.htm

Definitely quieter with the baffles in. What do they do for the testing?

Hi. Anyone here made a measurement of the db levels whilst having longshots on them? I'm in for the MoT next week and hoping theyll pass under 103Db
