I acquired a replacement pipe, and today had the "enjoyment" of fitting it.

To get the pipe off is a bit tricky, as it wraps around the driveshaft and is intertwined with the rear exhaust header. To untangle it, you have to jack the car up quite high (for ground clearance), then undo the clamp holding the rear header pipe to the rear manifold, undo the support bracket which is bolted to the cylinder block.

Then, after the clamps on the front header are undone, the rear header can be coaxed down and towrads the bak of the car by a few mm, which just gives enough clearance to ease out the front header and the repalcement in.

Those familiar with the V6 exhaust will have noticed that there is a short section of straight pipe between the front manifold and the pipe going under the engine. I could never see the purppose of having the extra joint, but it is now obvious that the extra joint is required to allow the under-engine pipe to be aligned correctly (as the engine block and manifolds don't flex very much).

BTW, the under-engine pipe is double skinned for most of its length, the holes in mine were in the double skinned part, but is still seemed to leak.

Well done Mike :D UI guessed it was going to be an "interesting" job. It's a bit of a devil doing it with the engine out and free of driveshafts so in-situ it really must be a trial :twisted:

Interesting on the short section. I did wonder if it was for the fitting of a pre-cat (the ES9J4S has them) but now I know :D
