    10 years corsa diesel - exhaust

    10 years corsa diesel - exhaust 19th May 19 at 3:33 AM
    It has mentioned on MOT since 2014

    2014 - rear exhaust box corroded

    2017 - nearside rear exhaust box casing corroded

    2018 - rear exhaust has minor leak of exhaust gases back box corroded

    2019 - exhaust back box deteriorated

    https://ibb.co/nL5WTjH

    By looking at the picture, how long has it got left?

    Quoted to 'renew the rear silencer' at 204 by halford

    Say I don't fix it till it 'fall off', would it cost more in future.

    I don't mind getting it fixed now, as the balance is just going onto 0% purchase CC, I just don't wanna fixing something that a) doesn't have to now b) it's simply wear and tear

    Get quotes from local independent exhaust companies.

    It only looks to be the outer skin at this stage. I would trim away the large flapping sections so there is no risk of them falling off and hitting another car. Then run it until the inner skin fails which you will know about by the noise.

    It could fail next month or you might get another year or two. When you replace it go to an independent as they will be much cheaper than Halford or kwikfit.

    The exhaust has a double skin by the looks of it. Mine is similar.
    Water gets in-between and then that's the outer layer.
    You can get under the car and remove all the outer that's rusting and should be good for a couple of years.
    I used an oscillating multitool, took less then 5 mins.

    If you do decide to get a new back box in the future go to a local independent exhaust place, I wouldn't expect to pay over 100.

    TWO HUNDRED QUID?

    Depending on the precise engine, the part could be as little as 40-50.

    Anybody who can't fit a back box in half an hour shouldn't be fitting exhausts for a living.

    Get a decent car and the exhausts last. I have a 99 plate Mercedes and a 2000 plate hyundai, both still on original exhausts after more than 180K miles on each.

    Higher mileages mean the exhausts are more likely to last longer - because they've always got properly hot, and boiled the corrosive water vapours off.

    Looking at that I'd say you have 2 months, 5 days, 21 hours, 6 minutes and 12 seconds.

    Give or take a year or two.

    Had my free Mot from them.

    But I did think I got ripped off for 48 replace both windscreen wiper blades and 22 for diesel common rail cleaner but hey no.....

    I definitely shop around when it's 200+

    As for the exhaust. I totally understand anything can happen at any time but its good to know there is two layers. I shall see if it get worse.

    So let's say 6 months from now, 'the inner skin falls which I will know about by the noise'

    Does this still mean I would only have to 'renew the rear silence', last thing I want is to wait and incure anymore damage/cost.

    Leaving it is unlikely to cause any problems. The only way I could see it causing any additional damage would be if the hanger came off and the silencer dragged something else off the car. From your pic it doesn't look like this is where the corrosion is.

    They take about a minute each to fit, with slightly less skill and co-ordination than using cutlery to eat.

    and 22 for diesel common rail cleaner but hey no.....
    Snake oil.

    Yes.

    Of course, we can only see that the back box itself is shagged. For all we know, the pipe forward of there may be on last legs, too, and it's worth getting the lot done at once.

    I needed to replace the original exhaust on one of mine a year or two ago - it'd lasted 20yrs from new, to be fair. The back box looked better than that one - but close inspection showed a slight blow in a couple of places it'd gone very thin. What actually failed on it, though, was the pipe fracturing forward of the clamp to the back box. The downpipe/cat looked absolutely fine at the time, so I didn't change it. It actually lasted about another six months.

    If one bit's gone, the rest probably isn't far behind.

    I'd change that sooner than later if for no other reason than to avoid the attention of the police.

    204 is double what my sis in law was quoted for an entire exhaust from local discount exhaust place.

    That's more to do with the annual mileage and type of journey than it being a decent car. An exhaust on a car that does long journeys will last much much longer than one that does mostly short ones due to the fact that on long journeys the moisture that builds up in them overnight gets burned off whereas on short journeys it doesn't get hot enough to.

    Another vote to trim off the loose skin and wait and see......it could last another 1 or 2 years
    Avoid Halfords at all costs they are nothing but a bunch of crooks along with Kwik Fit

    Clearly lesson not learned when I have booked my next free ish(10) mot with Halford. I would roughly estimate I have overpaid double of what it should be. So I guess that 35 paid for the free mot.

    I'm OK personally with them or even independent garage take a little advantage as long it is not blantly taking the !!!! expensive.

    Thank you all for the advise. I shall trim off the loose bit
