Should be 2.5". I could be wrong, but I'm fairly certain that the SLP is 2.5" like most of the other catbacks.

Your not going to lose any horse power you'll have alittle more power high end. Your car will feel faster because it will sound better.

IMO nothing sounds better on a Mustang than Flowmasters. They are very deep and aggressive sounding.
