Hi, I will be selling my M50 soon and getting a new '04 VZ1600. I will miss the M for sure as it is a great ride. I got a good deal on it (at least in my opinion) so I plan on making some upgrades as soon as I have it. My questions are: Is there any reason why I cannot make the exhaust/fuel/air mods immediately? Also regarding the exhaust...I would like to install either the Vance & Hines "Big Shots" or the Muzzys "Classic 2 into 1 megaphone". I like the "Big Shots" because they have a true crossover which seems to be what gives the best broad range performance (similar to a 2 into 1 pipe) according to what I have read. Does anyone here have any experience with either of these exhaust systems? Also how do you feel about the hypercharger versus other options? Thank you very much for your help.
