Chop off stock manifold flange and weld on T3 flange?
 

Does anyone have experience with chopping off the stock flange on a manifold and welding on a t3 flange? Can anyone estimate how much a shop would charge for this?

if its cast a lot of shops wont bother with it. i had 2 t25 flanges made for 35$. where i live at no shop would fool with it. i found a guy that welds on cast and steel i got lucky and found him. if you do find someone make sure they know what there doing when they work with cast.

Thanks for the info, is welding a cast manifold just a lot harder for some reason?

Re:Chop off stock manifold flange and weld on T3 flange?
 

a bit harder and not as pretty.....I'd just make an adaptor plate

Re:Chop off stock manifold flange and weld on T3 flange?
 

YES. its harder. first you need to heat the manifold and weld the flange while the manifold is hot.
