exhaust debaffling

Hi mate, did it on my Bonnie - I know the exhausts are different but I'm assuming the process might be the same.
You need to cut through the end plate that holds the baffle in place with a hole cutter (32mm on the Bonnie).
Then you need a socket the same diameter as the baffle, place it on the end and give it a couple of sharp taps with a decent hammer, this will break the 2 welds which hold the baffle in place further in the exhaust.
Next, pull out all of the fibre glass packing around the baffle held in place with wire clips. Use a long screwdriver to break it up and then pull out with long nosed pliers. Use a hoover to help get this stuff out - the metal tube of a "Henry" just fits in the Bonnie pipe!
You then need to pull the baffles out, but to do this you need to enlarge the area around the welds as it's hard to get the baffle to line up exactly with the break in the weld. Use a long screwdriver to push down the pipe and bend the tabs back - a good torch is useful here.
The baffle should now pull out - that's as far as I went because I didn't want to have to re-jet the carbs at this stage - but I did fit the Thruxton needles over stock to help enrich the mixture slightly.
It gives a very noticeable improvement to the sound over stock but you can go further by drilling the next baffle down the pipe, but you will need to weld a drill bit to a length of steel rod to reach it. Then you can increase the noise by the number of holes you drill but you may well end up needing to adjust the carbs or need a remap at this poit as the engine will start to run too lean because of the improved air flow.
Hope this helps - worth doing in my opinion.
Cheers Steve
