gmpp exhaust is basically a borla exhaust.
it honestly depends on how loud you want your car to sound. these two that you have suggested are probably the loudest souding cat systems for our cars. if you are going to upgrade your header and dowpipe, it's only going to be louder.... just trying to get you to look ahead.
gains are about the same for each system, so like i said, its all about how you want it to sound.
