Header to tailpipe flange???
 
Good afternoon, I purchase a new big tube header for the stb side. However , after receiving it i noticed how the flange ends are different from my previous set as l as the tail pipes.

these are clearly two different types but I’m stuck on what direction to go to make this work with what i have or if i need to have a new tailpipe made?


the set with soot on the end is what i have for tailpipes, any help would be greatly appreciate
thanks

Those are CMI correct. Looks like one is rope seal and other is gasket? Ck cmi website also.

I believe the top photo is a newer design. Does the bottom photo header connect directly to the tail or is there a piece in between the header and tail?

These are the tails, it was just a gasket and a v band clamp. So if the other is a rope style, is there anyway to get these tails to work??

from my understanding yes the newer set is CMI, older ones not to sure, no markings or info on them.

The newer header is just a gasket as well, but obviously the tail is beveled to the header shape. I’d call CMI and ask if they have a sort of adapter?

I have trs tails at cmi if in need let me know and I can put a call into them. They’ve been sitting there for some time now. This just reminded me. Also I have brand new clamps, gaskets etc for etops.

Those are not rope seal headers. Not sure why they have the angled flange instead of flat though.

they are straighter for transmission boats. You have Bravo drives?
