Going onto a motor where the rest is stock, catbacks won't make enough gains to write home about because they're not the bottle-neck. The more you have done to the car though, the more a catback will open up.
depending on the catback you could be dropping a somewhat significant amount of weight from the car (not enough to really matter on a daily, but if you're competing on track it'll get you that extra little bit)
Plus, some of us definitely think it's worth it just for the noise!
