Can you get it in 2.5? or is that what it normally is? I am having a bit of trouble finding the specs online. Checked the main site I didnt see the specs on it.

 

Its 2.5. The only thing is that it is a true Cat Back. meaning that you have to cut your stock mid pipe and fit it over with the provided clamp. The small piece of pipe that connects to the S pipe and the 2nd cat are the only parts that are not 2.5 in. Even though it bottle necks, it is one of the best exhausts for the tc that i have heard. Plus it does deliver some power.

 

and its expencive as hell too! cant forget that one.
