I have just picked up a spare set of stock pipes for my 04 ST3. I was thinking I might core them to get some more noise. Has anyone done this mod and will I need to do anything else to get it running right. Runs very sweet with stock everything so dont want to screw with that. Would love to unleash a bit more of that lovely Ducati sound though.

I got my ST4 mufflers cored by the guy that does them here in Christchurch, he done a great job and certainly unleashed more noise without affecting how the bike ran. After a couple of weeks though I didn't like how 'tinny' they sounded, so I bought some carbon fibre cans instead. Should've done that in the first place.

I did not have to tweak anything to suit cored or carbon fibre cans.
