those gains are unrealistic. you are likely going to gain maybe 1-2 at best! you are primarily buying it for the sound. I just installed a set of pypes muffler deletes on my GT and didn't gain anything but a heavier right foot cause it sounds amazing. and my pypes muffler deletes of SLP loudmouths are cheaper as well. you just have a nice and loud exhaust when you stomp on it and you need to worry a little about noise restrictions.
