Borla S

[Ron01864]

While awaiting my delivery of GT Premium (EDD June 1) i have decided on a Borla S catback system. I just havent decided on 2.5 or 3 inch pipe. I have been on a few exhaust forums with no clear consensus as i could not find one thread that was Mustang specific. Any thoughts on which way to go? Thanks for any help.

I would only go 3 inch if you plan to go forced induction.
