This is a great buy for someone that wants a more aggressive exhaust note. Can't say definitively that pulling the secondary cats and and resonator out of the exhaust stream will give you more power but logic says less restrictions and my butt-dyno said I picked up a few when I did the same to my car. And a $100? If I was closer and hadn't already done this, I'd be all over it. Someone in Texas needs to ****** this thing up!
