You're free to guess, I've left all-kinds of clues in my posts. I can make another one just like it, what it did is make my UFO 4/1 Dragstar a system you can ride w/o worrying-about losing your hearing if you don't use earplugs. I would equate the db to something not much-more than my stock exhaust, but the UFO still works fine, and I have the VBoost still operational. No throttling-down to the point of choking-off the exhaust, causing drivability issues, and you can actually-pass a LEO (law enforcement officer) while accelerating and not have to worry about being pulled-over for excess noise, exhibition of speed, defective or illegal equipment, or whatever code he can find in the state statutes.
I'd like to make one for another UFO owner but it's not cheap, about the same price Jon Cornell charges for his better-finished megaphone, which is still too-loud for my taste.
I can see where you could think it was from a Warrior, no, that's not it. I did some calculations about the canister volume and RPM's, and I am solidly in the functional area for efficiency, but I am not an acoustical engineer. In other words, for the size of the engine and the RPM's it runs, the volume of the can is supposed to be compatible. All I can say is that it allows me to run full-throttle bursts without making my ears ring as they would after riding with the stock UFO setup if I wasn't using earplugs. And, no apparent penalty in performance.
I started to make a post about a year-&-a-half-ago like Warp12 has recently-done, but my dyno dilemma http://www.vmaxforum.net/showthread.php?t=21873&highlight=dyno+dilemma interrupted my attempt to determine a baseline before I began throwing my hop-up stuff at it. This thread is probably my second mention of what I've done to the bike since the engine failed post-dyno. I did make one other accounting for $-spent. I've bought a lot of spares along the way, all-kinds of stuff, and my wife insists I could have bought a new bike for what I've spent, but it hasn't been that bad.
I had built a new master bath to placate her for the $$ I have spent, and it's turned-out nicely. As I previously-posted, you could buy a decent Hyabusa for what I spent for the bath remodel. It was fun though, because I did some cabinetwork for it, and it probably got done quicker than if I did it myself since I hired a neighbor to do the majority of the work. He did a nice job on the tilework.
