Here you go,all on here.Possibly wrap a little wire wool around the internal baffle then pack as much of this 'wool' over as you can to get it back in the sleeve.
If you dp not fancy doing it your self, give this guy a ring, he makes exhaust systems & does a lot of the systems for A16. He will repack them etc for a very low cost,
Teddy - if you want a compromise, ive got a set of brand new 50mm termignoni 'approved' silencers. These are half way in terms of noise between standard silencers and full on race - but have all the legal stampings on them to keep you legal.
I understand that the 50mm silencers can be fitted to the 748 by sleeving them outside, rather than the inside of the balance pipe - perhaps someone could confirm this ?
