It would make it easier to work with if you undid the nuts on the cat so then you can take the whole exhaust off in one go and get at it from any angle. Depending on how rusted on it is, trying to prise the joint apart from the slits might not work. I tried this once and it just ended up flaring the bits next to the slits and the rest was still stuck. | |

Yup it is a slide over join lol. Clean the pipes with some wire wool if you have any before putting your new back box on. | |

I'm not sure of how it's set up on a Corsa B but if it is a slide over join I normal put a screw driver in the slits on the exhaust and twist it to prize them open slightly. | |

When I was removing my exhaust before I nearly gave up. I found That It worked by constantly adding wd40 and moving it up/down and twisting it because the pipe is not a perfect circle so you have to keep twisting it. Place a wooden block on the exhaust and swing at it and then do the same for the other side. | |

Use a rubber hammer and wd40. Best tools for changing a Corsa or nova bb from underneath. :lol: | |

Ok, thanks for the replies. So it looks like I'll have to hit it a LOT harder! | |

As said, all you can really do is hit the back box to try and dislodge it and pull harder. | |

Beat the fuck out of the back box away from the system, you'll also need the twist it as well. But be carefull because you might break the flange on the cat. Which I've done in the past. | |
