wool for exhst

Hi guys,
Is it possible to change the wool for the closed with rivets exhausts, like Zirri and simonini ones??
THX!

HI THERE MARCUS, IF YOU MEAN THE TAIL PIPE IS HELD ON TO THE EXHAUST WITH RIVETS (3-4 RIVETS) THEN YOU CAN CHANGE THE WOOL JUST DRILL THROUGH THE CENTER OF THE RIVETS REMOVE THE TAIL PIPE REPLACE THE WOOL AND PUT IT BACK TOGETHER YOU MIGHT NEED TO USE SLIGHTLY BIGGER RIVETS AND REMEMBER NOT TO USE TO MUCH WOOL WHEN YOU PUT IT BACK TOGETHER OR THE EXHAUST WILL HOLD BACK THE POWER. THIS SHOULD HELP YOU . DANGER

OK, I guess I need a riveting machine or something to get the exhaust mounted back. No problem, many thanks Danger!
