So when you next change the downpipe I'd also replace that rear core plug.
I've had 2 spit ones fail (same engine but u can use the TT 4-2-1 on a spit) in the last 5 years...(same plug as the rusty looking one in your pics)

I got home once with a self tapper through the hole....and the second time I was lucky as I noticed it on the driveway.

At the bottom of the downpipe where you have fited the clamp should there not be a steady bar from the gearbox mount to the clamp?

Ahh I see it now, I didnt think that you would have forgotten an important part like that

Thread resurrection time. I took advantage of Rimmers VAT equivalent offer to get a replacement downpipe. comparing it to the POS one that doesn't fit the two are clearly different:


That's not conclusive that it will fit but if they were the same it would be conclusive that it wouldn't fit. IYSWIM
I didn't get the angle quite right for the side on photo, looks promising though.

Shame the new ones don't have properly siamesed pipes like an original. Next time I've got a couple of days spare this project can move forward.

Will a 1500 notice the difference between siamesed and trousered in terms of flow - assuming no other breathing mods? As long as it fits, then at least you're ahead of the game now.

I was thinking more about the space taken up by the joint, it's quite a bit more bulky.
