- 2005 Vauxhall / Opel Corsa C 1.4 petrol Twinport - exhaust manifold / catalytic converter removal - may be helpful to some as I was researching prior to removing it, couldn't find any info. They are the same as some 1.2.

really useful stuff mate! literally been looking around for a couple of weeks of how to remove the cat from a 1.4 twinport and there you are uploading it 3 days ago, perfect timing 😂
Glad I could help!
I took this off and replaced the gasket when I did my head gasket, but those bolts on the studs down the holes are a right bugger. 1st the studs were all rusted up, finally managed to get off, replaced studs, then getting back on again at end, more trouble. Now smoke coming from holes, so probably not tightened down right.
Much easier to just scrap the car and walk.
Not sure if you did, but every time they're off - the nuts should be replaced - they're made of brass if I remember correctly and are single use only, every next attempt and the threads may not hold strong enough; studs themselves should be ok to reuse, but nuts are definitely single use item. I agree though that it is not the best design.
@@signummotors Thanks, yeah got brass nuts, not sure the person who was in previously used them. The nuts were mostly rusted firm to the studs.
Got a new thin deep socket coming to try and get the nut down right. Its such an awkward design to get in there
Yeah it's garbage. I've just done head gasket today. I managed to get just one nut off which brought out the stud. Someone had used steel nuts, every one totally corroded and all fused together. Even if I'd managed to get one more out, those deep seated one's would have consumed too much effort.
I just took the head off with it all attached, it wasn't blowing before, it can stay like that! Not worth the effort to spend a weekend drilling, heating, swearing etc.
@@djtaylorutube That's the beauty of trying to do something right that someone else has bodged in the past, most cars are like that I'm afraid, especially these days.
@@signummotors Yes I agree and I have all new studs, new copper nuts but i'm against a time constraint as the car needs to be done by the end of today. The perfectionist in me wanted to remove all the old studs and fix it properly just out of principle but not this time. The sheer effort of fixing the top "easy to access" ones, let alone deep seated ones just had me accepting "not this time". It probably would have ended up with me cutting off the entire manifold/cat and replacing it all. Still, it did allow me to drill out the broken stud on the exhaust downpipe to rear and of course, one of the others snapped too just for good measure, the third was so corroded it needed grinding off.
As you say, usual faff for typical exhaust stuff.
I have some questions , do you have to jack the car up to do this and will it be the same for the 1.2 petrol twinport?
I had the car over a pit, so yes, you would need to get under it to undo three bolts on the exhaust and two e-torx on cat bracket. Or dig a little trench and drive the car over it, should do the trick... :) Make sure the wheels are blocked with some chocks and it's on axle stand and won't fall on you. This can be nasty, so it's best to be prevented. As far as I remember they are the same on 1.2 petrol.
