I must admit it looks great underhood, and it sounds better with a Rotofab.

I'm definitely not advocating people rush out and buy Rotofabs here. I was simply tired of the he say she say. I wanted to know for a fact that a) the car truly doesn't need a tune and b) does it add any power. Now I know. The air/fuel was safe and the Vengeance guys said it definitely made a few more ponies than they typically see out of a stock A10. I didn't buy this thing for big seat of the pants results. I like the look and the increased whine.
