Default 3" Cutout
Magnaflow cat will be arriving Monday (2/19), and will be on the car Tuesday. Trying to decide whether to get 3" cutout. If so, about how much hp should I gain with the cutout?

Most get a 3" cutout. That was what ALL of mine have been.

With Magnaflow, I doubt that a cut out it worth the effort. Especially if all you have is bolt-on's. Maganaflows are supposed to flow really well

I agree, Your not going to be able to tell a difference. Espicially with the Magnaflow, unless you just like the sound it's not worth the effort.
