Pre Cat removal
vRS_Pagey:
moderately tempted to have a go at this myself today, however I'm a bit concerned about breaking the turbo bolts........ :scared:
Bogwoppit:
My car has just sailed through another MOT emissions test without the Pre-Cat.
If you are DIYing this mod here are a few tips:
- Make sure everthing is cold.
- Spray some WD40 on the turbo nuts and the 1st Lamda sensor.
- Remove the 1st Lambda sensor before undoing the turbo nuts.
- Ramps or axle stands or car lift needed.
- New turbo nuts and the Gasket come to about £10, you might as well change them.
On a different note how much is Cat material worth at a scrappy as I have 2 Cats worth lying around somewhere?

Good info Bogster.......
Regarding value of the cat material, it will depend what car its from, BMW and Mercedes use far more precious metals in their CATs, tbh though I'm not sure a scrappy would be interested in the raw material, but no harm in asking.

Pagey if both your vrs and golf are diesels they don't have turbo bolts its just a clamp on the turbo to DP :happy2:
