ive been under the impression your sposed to tap the pyrometer gauge into the manifold, however ive seen people do it in the dow pipe too. my question is if i do it in the dow pipe instead of the manifold how much temp accuracy am i gonna lose. its really ust much easier to do it this way.

Not easier in the downpipe. Yes it is a way of doing it. I've seen it to be 300d difference in pre and post turbo. Pre being hotter.

There also isnt alot of metal in the downpipe its not very thick. So you wont get alot of threads tapped in there. Id be afraid of it falling out or leaking as well as it being off with the temps :rolleyes:
I'd imagine the majority of people would have a bung welded in though

i had one in the downpipe for a while and it wasnt very accurate, at wot it didnt get hot right away. after i had let off it would still be heating up.

I would just tap the manifold, much more accurate that way.
