very hard to remove cans

[bcadou]

Hi
I am trying to remove the original cans (to replace with CCC I have just received) but they seem to have rusted and are firmly attached to the other part of the exhaust. I have tried WD40 but I still can't manage to remove the can. Do you have any tricks/ideas to help me remove the cans? cheers

Mine had small pop rivets, 1 each side adjacent to the band clamps, holding the cans in place - an extra security measure I guess. Drill the heads off and knock them through.

thanks mate, mine doesnt have those rivets though

Take it to an exhaust specialist, they do this kind of thing all day and won't charge a lot of money to replace your old cans with the new ones. It just isn't worth the agro.

1. More brute force
2. Proper penetrating oil - not WD40 - and leave for a while before retrying step one.
3. Heat

I would first check the band clamps haven't been overtightened in the past and deformed the pipe from the can into a groove with the exhaust. Do the cans rotate on the exhaust pipe but wont come off? If not try a band strap on the can spigot and make them turn, if you can turn them back and forth your half way there. Personally wouldn't touch an exhaust garage with a barge pole unless you know them very well or they let you watch what they do. Best of luck.

I said "Exhaust Specialist" - not Kwik FUK!

I ended up prising the ends of the pipe on one of my cans up and then bending them back with pliers like peeling a banana, if that makes sense. After a bit of twisting and pulling the can came off. Put your foot against the corner box when pulling to make sure the force is on the right joint.
