OK, done, for the most part! I have one of my two cans for my UFO 4/1 installed, and I think I am likely to leave this on for the time-being. I know my neighbors will appreciate it. :biglaugh:
I have two different Jap big-bore exhaust canisters I adapted to my bike. I am waiting on a gasket for one but the other I installed today. Here are a couple videos.
The #1 thing I hoped to accomplish is to quiet the
UFO 4/1 w/o losing throttle response, power, or having to re-jet. I haven't ridden it yet, but here's proof it can be done. I did this today, and while there are some small details yet to be accomplished, I am going to road-test the assembly after I post this.
I wasn't expecting any great breakthrough, I am a guy puttering-around in my spare time trying to get my bike to be more of what I want. I like the
UFO Dragstar 4/1 I bought, a Jon Cornell
UFO product. It was a bit loud, so I got the megaphone made for me by Jon, it's still loud! So, I decided to use some of the parts I have accumulated. I adapted a big-bore Jap sportbike exhaust stock canister (I have two, from two different bikes) to my 'Max. It works.
The first video is just a static shot, but the second is w/the engine fired-up. Guess what it sounds like? A stock big-bore Jap. sport bike!
The best thing is that it is quiet, several magnitudes to the 'quiet' side of the Likert scale (1 to 5, 1 is 'really-quiet, for a 1000+ cc Jap. sport bike, or a stock exhaust, typically; to 5 where you are running a
UFO 4/1 Dragstar w/the shorty 'bologna-cut' "muffler," and I use that term "muffler" loosely).
Before it was a "5!!!" and no-doubt about-it! Now it's a "1" or a "2" so if you don't want to wear ear plugs every time you ride, in the interests of saving your hearing, this is a "good mod."
If someone w/a
UFO 4/1 was interested, PM me as I think I could duplicate this pretty-easily.
And for those of you who subscribe to "loud pipes save lives," here is the real-thing, a
Dragstar UFO 4/1 in all its glory, running on a
Dynojet Stage 7 set of carbs.
Now you might say, "well we didn't hear anything in the way of the canister-equipped bike running-hard," which is why I am posting this and going for a ride.
unk: I'll let you know how it goes. I can tell you, the muffler can is mounted very solidly, and I don't fear having it come-adrift on me during my road test. As "Uncle" Tom McCahill, who is generally credited with inventing the formal road test format for cars in the post-WW II economy, might have said (he was very 'politically-incorrect')
"I'm going to 'cane it' like you would a lazy Bombay houseboy, and then I'm going to celebrate with a Beefeaters gin & tonic!":rofl_200:
Update: After a road test, I am perfectly-content to leave this canister on my
UFO 4/1 headpipe/midpipe. It appears to ride the same as the much-louder
UFO, whether you have the "bologna-cut" Dragstar "muffler," or a
UFO megaphone w/either of the two rear cap open-diameter measurements.
By "ride the same," I am referring to throttle response, quickness to accelerate, steady-throttle operation, and ability to pull to redline if you are choosing to make a 'banzai-charge' from first gear. Now I am not a person who practices 4-5OOO rpm drag-racing starts like Sean or Kyle, or any of the other guys on-here who do recreationally. I don't avoid giving it a good workout occasionally after doing a normal clutch release from a stop, assuming it's a clear road. I did manage 8K w/the new exhaust can in 5th merging onto the I-95 expressway by the FT. Lauderdale Airport, where you have a good view of traffic ahead, and the bike pulled flawlessly to redline, or as-close to it as I came in the lower gears, and it was showing 8K when I backed-off, so except for not doing a holeshot, it was probably roughly equivalent to a 1/4 mile strip run.
Where before it sounded like a big-displacement V-8, bellowing along, now the intake sound and the wind sound are about as-loud as the exhaust note, and after living w/the
UFO 4/1 in all its unmuffled glory (I don't consider the
Dragstar "bologna-cut" exhaust tip to be much of a "muffler") and being able to treat all the Daytona Beach Harley riders to the sonic benefits of a
Stage 7 UFO-equipped VMax, w/a
Dragstar tip, I think I prefer the current setup I have "Frankensteined" together. Oh, be assured that when 2014 Daytona Beach Bike Week comes-around, I will be removing my sportbike exhaust canister on my VMax, and will replace it w/the
UFO megaphone. Someone has to show the
"Tuber-tooters" ("potato-potato") what a powerful bike is supposed to sound like, if you run straight exhausts. :biglaugh:
