Hi
Further to my exhaust welding dilemma.

Can anyone please tell me what diameter piping to use on the 4 branch.
I am going into a 2" silencer pipe
The engine is a standard 1800 pinto.
I was thinking about 1.75" but looks a little big to me.

Also what wall thickness?

Cheers David

38 x 1.5 wall .

Ta!

If you are doing it in Stainless, then the if you use the 38mm you will find that if you carefully dress one end of the pipe to a box section, if will fit nice and snug into the oblong hole in the flange and then you just need to seem weld round the pipe/flange joint to make it a good'un.

I know 'cos that is what I did.
