Hi,

I just wondered if anyone could help me, I am attempting to change my catalytic converter for a new one as the flexi pipe has had it. I have changed these on a couple of different cars in the past but the 406 seems to be a different animal! There is so little space to get to the front joint where it meets the turbo and after struggling in the rain for several hours to get the middle section joint undone now I have found that I just cannot get enough space to pull the section out. I can see that there is an overlap of pipe so I need to move the cat forward to disengage it from the middle section, but with all clamps undone and the bracket which supports the exhaust I just can't see a way to do it. I'm doing this on my own using axle stands which I know isn't ideal but I thought I'd be able to get it done. Also, I'm not looking forward to trying to get the new one in after seeing the limited access! Any ideas or experience of the process would be really appreciated thanks.

anyone?

Its something I've never changed on a 406.
But hopefully some will give you a guide soon,

Where abouts are you located mate
If your local I sh. To Manchester I'll lend a hand

Yeah, it's a bit of a pain but it's not impossible. I think I undid the mid-section clamp first to loosen it up - push the mid-section bit backwards after undoing the bolt in order to separate it.

For the front joint, it's best to use a ratchet - I used a normal spanner but it took me a while due to lack of space.
