Ok 3 Wheeler's today I was very bored and decided to remove my silencers to look at drilling the first solid baffle plate. After an hour of looking for bits and bobs to make a three foot drill extension and then another trying to drill I gave up and put everything back together and went for a nice drive. So what's the secret best way to drill the plate or do I just ring garage 56 for an early Christmas pressie? Cheers Paul

You need a 38mm hole saw & a 600mm extension or 2x300mm & cutting/tapping spray. Check your chuck is big enough, I had to borrow a variable speed drill.
Drill very slowly with frequent application of cutting spray. Dont pull out to check progress as it will be hard to relocate the cutter. Neither of the discs I cut broke off but bent over. No rattles so they must still be there. I only needed one cutter but others needed one per silencer. This needs patience as progress is slow.
I'm pleased with the result, car seems to breather better & I'm considering a Garage 56 air cleaner but £200 is a lot for what it is. Yes it will be louder but at steady speed hardly more noticeable so not likely to wear you down on a long journey.

Or, do what I did, drill some holes in the front baffle. I would suggest some 9 - 10 mm holes, nicely spaced. Start with four of them. Use the impact setting to get the bit to bite, so to speak, otherwise it takes forever.
You can use that method to punch through the center when hole sawing as well.
M3W, now!!!

i got bosch hole saw worked better without pilot drill in middle,self locates on outer edges in side the pipe ! very slow with high power battery drill(dewalt).WD 40 as coolant /cutting juice. slow n steady wins the race!!!!!!only a few min"s each side longer to remove than drill!!!!
