Removal of rear Cans

[anonymous-user]

Ah
They are stuck solid. Have tried to turn, soaked in WD40 and tapped them with a drift.
SOLID

Any helpful tips please?

I found the technique was to sit behind the car, put your feet either side of the can on the rear box and then pull and wiggle or rotate it at the same time.

Get a screwdriver/chisel type tool and using a hammer prise a few of the tails of the cans away from the exhaust, spray lots of lubricant WD40 and then do as above twist and pull at the same time until you face goes purple /blue.

If they still dont come of take it to local tyre exhaust centre and they will get it on a ramp and remove in ten minutes using the technique above. Get them to fit the replacements and it won't cost much £20 cash in hand. I paid a £10 but then I had just got him to fit 2 new tyres to the Mrs car a few hours earlier.

When I did mine a couple of years ago the only way I could work them loose was by subjecting the cans to a lot of heat! I made up a metal plate to protect the bodywork then used a gas torch and blasted the pipes, one at a time. After a bit of heat then spraying cold water and a lot of persuasion they came off!

Think this is the way I'd go too.

Amazes me that folks use the 'Silencer Gum' on this joint.....and then have sleeved cans??
I've just used copperslip when I took mine off.

Some are spot welded on. You can pull all you like but if welded you won't get far.

Also, be waey of damaging the joint between the pipe and the back box. This is a known weak point. I had mine reinforced.

Looks like I need to find a good and local exhaust place.
flanges opened up and soaked in penetrating oil, and rock solid still, they wont budge.
Need heat I suggest.

i tied all of the above! local exhaust fitting bay, oxy heat and hey presto, best £15 ever spent.

Can anyone reccomend an exhaust specialist Nr Horsham. I can travel a bit.
I tried all the suggestions including my own heat with heat mats in place and even when red they wont move.
I went to my local place but the conversation with the fella was too scary for me to trust him.
he likes hammers and had not much of a clue.

any suggestions.

Not local to Horsham so can't help there but did you have a look to see if they had been tack welded in place?

Spent ages trying to get the previous by pass pipes that were made up for the Sag to sit properly and they always returned to the same slightly downward angle.
When I eventually went to change them for some purpose made short silencers I found the garage that made and fitted the by pass pipes had tack welded them on, had to have weld heated to remove it.
Would have thought that your local centre with some heat and a block of wood to protect the silencers should be able to remove them quite easily. Standing around and helping them, should stop any attempts at butchery.

Not got those cans fitted yet? Thought you'd be upsetting the neighbours by now

I don't normally recommend them, but have you a local Kwik Fit nearby? I gave them a call when I originally changed mine, they offered assistance (heat) in exchange for cash, but on a second look found mine had been spot welded on so resorted to a grinder rather than their services. Still required a lot of twisting and pulling to get them free though
