I got the one that ends in 101. I know it is center in center out. I think it is 2.25".
If you are going to eventually get a supercharger and headers you might want to consider getting a full exhaust with larger tubing. That way the supercharger could breathe better.
However I really like my Vortex. It's definitely not as loud as a V8 with a muffler, but it's pretty loud. After 50 MPH it really dies down and it does not have a drone.
