I expect nothing less of a 20 year old car really but i can't get the bolts undone that connect the cat and the exhaust manifold together. Basically they are just freely spinning, the clever design that's meant to hold the top with the pressure from the spring seems to have failed.

I have managed to get a 10mm spanner on the top end to try and hold the bolt but even that is struggling to get a grip, it's a real seized up nightmare Sad

Has anyone any good ideas on how best to remove these bolts given the access is tough? Id like to just snap them off if i can as i assume new ones will come in the cat fitting kit from pug?

Cheers all.

Hi buddy. Take the cat off from the middle section then push the cat fully one way, while holding it over you can undo the other side nut. Hope that makes sense? I usually use a battery gun too, always works for me Thumbs up

Hadn't thought of that one, thanks, will improve access for sure Thumbs up

I'm a little bit worried that it's all seized together though so even with better access to the top nut it's unlikely to come undone. I will get some anti seize stuff on and give it a go.

Not for better access. When your pushing the cat one way it puts pressure on the bolt so it can't spin :-)

They are an utter twat once the bolts have been on a long time. Many heat cycles, wet etc and they are just s**t. The Ph2 Xsara fitting is a much better design and I can't understand why this wasn't used from the start.

Anyway, the method Ryan has mentioned has worked for me in the past. On one car, I got up to the bolts with a Dremel with a cutting disc.,

Yes, the new cat fitting kit has every. Fire ring. Bolts, springs, plates etc

I have used a P2 VTS manifold on a GTi6 before with a flexi fitted in the downpipe it is a much better design.

Dremmel cutter in the accessible nut it will all just come away then buy the kit on eBay £15 for full kit
Easy done
If you want to use your crusty ones soak them for a day or two with some wd40 or GT85 spray then try again
Dot drive it whilst soaking obviously!!
Definitely advise to replace
