Anybody have a source for 3.5in in/out? Or can fabricate the female end with 2 bolt flange.

I inquired about those. Probably the same as my existing Flowmaster set. Apparantly Dr.Gas had them at one time too.

those are adaptors going from a 3.5" round to a 3" ball / cone connection

[rp930]

You can select 3 1/2” in and out.

I know, they insist 3.5 to 3 in only.

Isn't Dr Gas and Spintech the same company?

---Boyd Butler has been Dr.Gas---but he closed up his business just recently.
---I don't know for sure about the Spintech business---but I think Boyd originally came up with spintech muffers.

I think a good keyed v-clamp is the answer here.

I looked for the same thing. I found that semi's use them, or use to. I found a part number on line, but had a real hard time finding someone that could get the part.

V-clamps work great...except for the broken clamps because the stainless nut galls the stainless stud, and then the nut seizes and the stud breaks.

Install a brass nut, or use a heap of anti-seize.
