1st gen Exhaust Diameter rear of the collector...

[jdbaker.vet]

Can someone help me with the diameter of the pipe rear of the collectors? I am going to fabricate my own mid-pipes to fit the RKs I just got and bend them just need to know the diameter?

 

Thanks in advance. And yes when I'm done I plan on making some set's to sale here on VR.

I finally found my collector and can give you the measurement. The rear exit where the mufflers connect to is 38.10mm, which is just slightly under 1.5". That's the outside diameter.
