Hi, i have a set of gt spec copy 3 bolt headers, that have badly cracked round the 3bolt flange weld. I want to change them, but will the up pipe itself need changing too, or are they standard/interchangeable? The reason is, the up pipe is wrapped, turbo blanket too, so a pain to get off.

Thanks, Tim

 

If you get another set of 3 bolt headers the up pipe will be fine to reuse Tim

 

why not reweld them, heat wrap may be the cause of the crackin, mine done the same and thats wot i was told helps cause the cracks

 

yep, becouse the wrap keeps the heat in. loosens the welds

thats another reason i stook to cast headers in the end. less fathing about

 

Cheers guys, it's a pain as not is next week! I thought about welding them, but I can see another hireline crack on the head flange too, so don't think they're much cop!
