CMI split tube clamps.
 

Hello all, I have a question on my CMI Split Tube headers. I bought these used and needing to know what clamps I need when connecting the tails? I think someone one said they had a second design for them. They are 4.5 tails. Also where is the best place to order them. Thanks, Timmy

Looks like a rope seal ? need a close up pic of the flange, could be v-band

Those are slip fit, no clamp. You put a bead of silicone around the header, then slide the tail over it. A bolt through the 2 brackets holds them together.

I'll get close up pics tomorrow. Just to make sure.

This may just be what your in need of, for the split-tubes

Yes that's the one's I'm thinking too. It looks like the tails could go together just a little more but that's as best I can get them.

yep ice is correct. The first pics looked like they were similar to the stellings slip fit.
