Hi Steveie . Does this method alter the function of the bike in any way. Ie back pressure etc.

i pinched this pic from another forum, but basically you drill it like this, then use a bigger drill if you want it louder ,then if you want the end baffle removed completely ,use a hole-saw, or sharpened screwdriver or chisell to go from hole to hole
Use a centre-punch to mark the steel before you drill the holes ,it'll save the drill sliding about.
It caused me no problems at all mate, if anything the bike seemed to run even better,.......in the end i linked up the holes and removed that part for a much louder deeper sound
