[736cc]

dude, I can make you one.

you want it to be deep and clean? or raspy with a buzz on deceleration?

it looks like a cone, give me some measurements at 8 inches from the opening.

[Sam Green Racing]

sorry but you've got me baffled

[Industrial Cafe]

oh sam, you're such a commodian

[Sam Green Racing]

It's having nothing to do thats the problem

[DammitDan]

Sitting on the "LOO" (sp?) is something to do, ain't it? 

[Industrial Cafe]

hmmm, sounds like I'd need the end cone to do it right...

I should make a video on how to make one again, I use sheet metal, a thick stainless pipe to roll the sheet into a tube, a drill, a bench vise to bell out the edge, and a cylindrical punch to angle the holes.

it's pretty easy if you have the patience.

  Kerker end caps are available but they're 3 5/8" dia; wonder if that 1/8" makes it too small. And I think I need more parts like a perforated tube the wrap fiberglass around? Don't see how that would attach to the end cap.

PLEASE do make a video.  I've got a 350 twin that sounds like a 1200 sportster with drag pipes on it and it is painful at high rpms.  Need to make some baffles to get it tuned right too.  I just threw some baffle wadding in the pipe to help but it made it sound kinda crappy and isn't precise enough that I want to spend time re-jetting.  Looking forward to learning something new...

[MCRider]

Likely you will need to have it made.

Let industrial do it.

or...

Easy to find universal baffles, Google them.  then

I used a long style CB750 baffle from the early pipes. I had a machine shop cut 2 circles of metal the diameter of the tube. Yours is a megaphone so it'll take a little measuring and trial and error.

Drill the circles full of holes. Weld them on either end of the baffle. Slide the bafffle in and tack weld it, or weld a tab on the outside circle that will match up with the hole in your megaphone.

A tip is not needed, though that is a nice approach as well.

I'll get on it as soon as I get home. (I'm on a road trip)

[736cc]

Keep in touch, ur efforts appreciated. I'll hit-on a bike salvage yard in the meantime and try to find a cork to stick this thang

I am having a complete change of outlook and I'm not sure how far to take it. I always put down the loud HD's that ran around with all that noise. All my bikes run stock pipes or something very similar. I used to call the magna the sleeper since it was very quiet but  could beat most every cruiser/touring bike it came across. Only the big sport bikes could take it on. BUT...after getting hit by  a big truck back in May by a driver who said she didn't see me, I have been told by some of the owners of those loud bikes, that if mine was a noisy as theirs, she might have heard me and looked again before pulling out.  Well, sure enough, the other day I was driving through one of the many small towns and stopped at a stop sign. The road to the left of me was a blind hill and that traffic did not have to stop at the intersection. I didn't see anyone and was just about to pull out into the intersection when I heard a loud bike. Hit the brakes and sure enough, a HD came over the top of the hill and went right through the intersection. Had I pulled out, he would have T-Boned me in the drivers door at 35 mph. So....I'm thinking I am going to start making my bike a lot louder. Might pull all the baffles out and re-jet.

[Industrial Cafe]

a loud bike is teh secks.
 mine has a shortened tailpipe on a yoshimura header, with a homemade 4'' long baffle that puts out 130-something db.
my kids know I'm coming home before I get into the neighborhood.

Loud pipes save lives is a myth . . .unless it is maybe preventing you from beeing hit from behind at full throttle. Be kind to the rest of the world & do what last owner of my CB360 did not do . . . keep it reasonably quiet. Crazy loud pipes & people who think they are necessary are the reason that most places treat loud bikes just like window rattling stereos . 

[736cc]

  My fav thing to do w/ a motorcycle is play w/ it; that includes many ways of doing so: riding, detailing, modifying, restoring, matching rpm's and gears, winding it out, leaning it into a sweeper, cruisin' w/ the bros, AND playing w/ the exhaust note. Its like playing a musical instrument when the bikes in sharp tune and you know how to throttle it just right. The CB750 makes all the right noises, (especially w/ a set of HM300's), and I really get a kick outa hearing my Yosh pipe on my cafe, and now THIS puppy comes along w/ a hot-rodded motor and open headers. I have a 5hit-eating grin hearing this thing light-up.
  I'm also in the early stages of losing my hearing. Guess 35 years on loud bikes will do it. This bike literally HURTS my eardrums when I crack it wide-open, it needs a little toning down. Cops will give me no slack if its the wrong cop.
  And too quiet is not what a bike like this is about. Quiet works on modern bikes; vintage bikes need some MODERATE noise.
 
  

[Rampage1967]

I agree about the moderate noise 736.
Yes 35 years of loud bikes would contibute to bad hearing.
If it hurts it is doing damage.
I wonder how many of the owners of those mobile base boxes will be like me when they are my age & have a pair of expensive amps in their ears (hearing aids)??

[Industrial Cafe]

heh,
      I also have a 4000watt stereo in my car...  
i like to feel it in my chest (in the gas station bathroom) when it hits.
             j/k but seriously,
I'll probably need hearing aids when I'm old.

that's kindof a broad statement, when you just got done reading some examples.

aaaand...

I was trying to be funny as well as making a serious point.
Although, my neighbors tell me they never notice my loud bike as I come & go.

its because you are new. once you get past 100 posts the quote feature will work properly. It also helps to smear vaseline on your keyboard.
