What is the OEM exhaust size on the SS?
 

Yep, that's it. Just wondering what the stock exhaust size is so if I were to get the cut-out I would know which size to order.

2.5 inches

For some reason How'd I know you would end up getting the E-cut-out...LOL good choice DMH correct?

Suggestion on the E-Cutout. Because the baffle is exposed, it has a tendency over time, to pick-up crap from the road which then inhibits a good seal, creating an annoying exhaust leak. If you add a short extension pipe to the end of the cut-out it'll help protect the baffle and prevent that.
