As far as the exhaust is concerned: the zard system seems just as short and stubby as the modification I am proposing. Maybe mine won't sound as 'good' and maybe it will be louder than the zard but, really... by how much? I am not sure that it will differ in too significant a manner. I have seen the zard and w/o the db killer it looked like the equivalent of a straight pipe with a little baffle in it, not unlike the one I am proposing. At the same time, by doing it this way I can save myself the $1200 that it would cost me to get a full Zard system (02-03's don't have slip ons). Seems that, like Crashmasterd said, if I get it tuned it should run just fine. If this set up lets cold air into the valves then so will the Zard. Again, like Crashmasterd said, this shouldn't be an issue: with the header pipes and the connector and the stubby baffle it seems that there will be enough pipe to stop this from happening. Additionally, although my set up may be loud I am sure it isn't any much worse than the busses, construction trucks, other bikes, cars with loud music, screaming kids, dogs, etc. I have in my neighboorhood now. And as long as i am not effin around on city streets I am sure I will be fine.
BTW Dr_Gallup, it is ironic that you would give a grown man advice on this topic in such a negative fashion. Telling another man to grow up is itself childish. I respect that you have a different opinion than me but I don't appreciate you telling me, or anybody for that matter, to "grow up." You don't know me and you have no right to judge me. I am sure you wouldn't agree with a lot of the things I do, BUT, that is what makes this country so great... it doesn't matter to me and I will continue to do them. Furthermore, I didn't ask for your personal opinion on my maturity... all I wanted to know is if my bike would run the way I want it to after some modifications. To make the situation personal and to attack me instead of the topic is what I consider immature.
