Exhaust size

 Tue 22 Jan 2013 11:14:42 PM
I'm sure it's been asked before but I'm a lazy fucker.
What size is the exit after the second cat? I'm thinking about straight piping and having it go under the rear axle that way it only has one kink. Very, very loud that way.

I'm thinking about a 1 and a 1/4 inch straight pipe from the cat back, what the stock diameter of the pipe after the second cat
