So i have a fletcher exhaust and it has a 2" diameter link pipe. Havent tried fitting it yet but i believe it wont fit to this manifold i have, http://www.minisport...w-manifold.html

Its 1"3/4. I think this is what i should have http://www.minisport...arburettor.html

Is there anyway i can make the 1"3/4 3 branch bridge to the 2" link pipe. or do i have to get the large bore LCB?

The fletcher should fit with the standard bore LCB, I have the 2" large bore LCB and I had to use a joining pipe as both the link pipe and manifold were the same dia

Ive tried fitting the link pipe to my manifold but the dont fit right because my maniflow 3 branch is 1 3/4 inch whereas the link pipe is 2 inch. Not sure what to do?

Hmm, well I used something similar to this (mine better quality but I can't find one for sale)

you may find one with 1 3/4" one end and 2" the other end? Otherwise you can get converter stepped sizes
