When to replace an exhaust

arcon5

Can't you buy sleeves or whatever they're called now and weld them in place rather than replace whole sections?

If the exhaust has rotted through, you could find it hard to find anything strong enough to weld to.

Had a new exhaust (back box and mid section) fitted two and a half years ago which came with a three year guarantee.

It has already corroded pretty badly and is clearly going to fail soon, but the garage has said their guarantee won't kick in until it actually fails. That will probably be shortly outside the guarantee period.

The previous exhaust lasted around 12 years on the car, so I'm a little annoyed that this one has nowhere near that lifetime and will likely fail shortly outside the guarantee period.

As I understand it the sale of goods act covers a reasonable period up to 6 years and a product should be of satisfactory quality.

It was highlighted at the MOT that the exhaust system was corroded (but not blowing) which is why I've become aware of it. I don't think it's fair to wait until the guarantee expires and then have to pay for a new one when it should have lasted a lot longer, in line with a product of proper quality. Any advice would be welcome.

As others have said, the MOT could have highlighted a "rusty exhaust" hoping to drum up some work.

It could look like that for several years before it starts to blow.

As you say it could be ok for another year or so. It looks like the outer layer has already peeled away:



I know it's difficult to say based on a photo but I'm interested to know from your experiences with your own vehicles, how close it may be to actually failing (blowing).

This is how things look at the silencer end:

You can clearly see the difference between the cheap pipe used for the actual tailpipe and the decent quality box behind it. Both of those pics are fairly cosmetic, although that elbow certainly does look a bit tired.

At least it actually fitted. That's always a plus for cheap pattern systems.
