ie by following above instructions then rewelding new flange/disc on to the baffle where you have drilled it out drilling three holes in that to correspond with the existing allen bolts and there you have bolt on/off baffle In fact I'm going to try it and will post pics if successful

That would be great!

At one point I realised I got too much attention from those I didn't want attention from..... Putting in a db-killer I got from ebay didn't do much difference at all. Now I'm back to the stock pipes, but a little more boom from time to time wouldn't hurt.

If the dB killers don´t do much the cans often need a repack...

Just wondering how big a drill bit you used to make the holes in the baffle plate?

It may be silly and little, but even how hard I pull it's still stuck...

Mine wasn't welded!

Nor was mine.
It was a little stiff , I had to use both hands and tug it quite hard, but it came off eventually.

if you pulled it off get to the hospital quick

Red Bobbit?

How they sound when they are wide open:

Performed a bafflectomy. Started with the whole fully covered with a perforated sink strainer which sounded much better than stock if a tad quieter than I was hoping. Moved to a central hole of about 26mm ( picked as it happened to match the size of the perforations and a hole saw I had) which was louder but strangely annoyingly so. It was giving me a headache. When removing these "baffles" the annoying pitch disappeared to I went the whole hog and opened out the strainers to about 48mm. The strainers are really just there to cover the untidy debaffle work underneath. Its a lot easier to tidy up the soft aluminium than the stainless cans. The results are near perfect to my ear. Loud but not obnoxiously so.

Some mates at work were interested in hearing the result so I took the bike into the underground car park for a show and tell. After it had set off 4 car alarms they gave it the official thumbs up.
