Been meaning to do it for a while so ordered the 3 new clamps and 4 new bolts for downpipe in case the old ones snapped. £60 from dealer.
Removed center section of exhaust. You only have to take off the left downpipe as the right has a clamp just before the secondary cat.
I then cut the heat shield off (only the top half ) with a thin cutting disc in a small grinder. Following that i cut a square hole out of the top of each cat ( this is all done from the top ) After removing the plates i cut it took a while to dig out the stuff (its harder than you think ) Give it all a good scrape out inside. Then just welded it all back up. Took about 3 hours from start to finish.
