Well, maybe not WAYYYYY.....but the P5 does 0-60 in like the mid 10's (correct me if I'm wrong, been a long time since I read anything on the p5), and the MP3 is mid 8's. Factor in the extra weight of the p5, center of gravity.....yup, slower. Don't get me wrong, I love the p5, heck I was in the process of buying one, then the dealer found out just before I signed on the dotted line, that there were 2 mp3's coming in. But, your gonna need more then just an intake and some exaust to catch an mp3. HP isn't the only factor.
