Borla's
Hey Nuke I have the Borla's and they are nice.
Sound: you won't notice a change until you punch it over 2500 rpm, then it sounds like a beast the higher you go.
Performance: I have noticed a +1 mpg change with normal driving conditions. I don't have that slight hesitation when accelerating from a stop or on the go.
Installation: Getting the old off was more difficult than putting the new on.
