    Astra G - Exhaust Blowing

    My exhaust has started making a blowing sound when not at idle...

    ...It is a smooth, beefy sound almost like I have fitted a boy racer exhaust!

    It is about 3-4 years old, so is that the normal lifespan of an exhaust for a vehicle driven approximately 15,000 miles a year with mixed driving (some town, some motorway)?

    Is there anything I can do myself to repair it on the cheap? Like find any holes and fill it with glue or wrap it in duck tape?

    I'm not going to replace it until my MOT at the end of the year if I can help it, so that I can save up.

    I am surprised that the emissions light hasn't come on though, I thought these sophisticated, modern cars are supposed to detect problems like this...

    Mine went after about 3 years on my MK4...SS now so no more issues with rust

    Duck Tape will melt by the way...

    Thanks mate! So the advice is to pay a bit more and go for stainless steal? Roughly how long would one of those last then?

    I knew that which is why I put the ROFL smiley in, but thanks for clarifying it for anyone that saw this and thought they would give it a try!

    you can get a thing called exhaust bandage which wraps round any holes etc to seal it

    they sell it in halfrauds

    Stainless is lifetime really

    although if the flange fixings are made of mild steel which a lot are nowadays they'll last a few years, and can be replaced for a couple of quid too

    Seriously? So if I fitted a stainless steal exhaust, it would never need replacing for the life of the vehicle?

    Why aren't they fitted as standard then? It would save a lot of landfill...

    technically yes but as said the flange will corrode and you'll still get that lovely blowing sound



    Solution...have a s s one fabricated

    i have had a stainless steel exhaust for over 4 years now and i have never had a problem with mine.

    they do change colour slightly because of the heat but they never ever rust.

    the reason companys never fit them as standard is to keep costs down and in my opinion i think its to make more money so you have to replace it more often.
