Any thoughts about the lambda sensor location from those that understand this sort of thing?
Certainly get the impression that my DIY idea might not get good results as far as a pleasant sound is concerned. Anyone got a spare ACT or Clive Y piece they want to sell?
I think there is a picture of the single lambda on Derek's new build thread. Certainly get the impression that my DIY idea might not get good results as far as a pleasant sound is concerned. Anyone got a spare ACT or Clive Y piece they want to sell?

In most peoples mind a modified original CAT Y-piece is not a nice sound.
Getting a decat Y-piece from either ACT or CliveF is by far the best route.
Two main reasons:
1. They sound much better.
2. You can retain the original for MOT or future sale. It WILL fail the MOT once decatted.
Mine went through the MOT last October for the first time without cats and was tested as a "'94 non-cat vehicle" ... passed with flying colours.Getting a decat Y-piece from either ACT or CliveF is by far the best route.

Just to close this thread off.
Got a Clive Y Piece from Barrie. Many thanks.
A local TVR owner, Alan641, popped over today and helped me remove the nearside manifold (gaskets needed changing) and replace the old standard Y piece for the new one. Getting the old Y piece out was more of a struggle than getting the manifold off which was a welcome turn of events given the bad experience some have had with the manifold bolts. Job done in about 4 hours, including a bacon sandwich break. Thanks Alan for your help.
Sound is pretty impressive compared to the original.
