I am installing a set of ARH 1 7/8 headers with their catted y. I'm doing this on jackstands and so far I have the headers and y bolted up. I've hit a roadblock as I cannot get the ARH y to connect with the int. Pipe on the dual dual. Looks like both are the same diameter.
I've searched and cannot find this exact issue.
Am I missing something?
My next move was to try to remove the pipe and take it to be expanded but it looks like it has a nice crimp in the it from the clamp so it may be a bear to get off.
Any help would be appreciated

Since you don't have any replies I would contact ARH directly and see what they say and go from there. They're system went on fine for me with the Borla system.

Definitely contact ARH. I had an SLP dual dual on my car for a while and installed a set of 1 7/8" ARH and their ORY and didn't have any issues.

Thanks guys, after heating, beating and pretty much doing everything I could think of, I was able to get a band clamp on the ends. This is holding everything together pretty well.
I'm going to take it to the local shop this week and have them fix it up right.
