Hello everybody out there!
The Touring-models, like my 96 Road-King, have the left exhaust pipe from
the rear cylinder connected to the right pipe.
Does anybody know why? What happens if I remove that connection between the
two pipes?
There are aftermarket exhaust system where each cylinder has its own
separate pipe. So what is the advantage/purpose of connected pipes?
Thanks a lot and enjoy the rest of the season,
Chris

There won't be a connection between the two pipes anymore :P

It's a crossover pipe. The advantage/purpose of a crossover pipe is more
torque at lower revs. Harley still uses this crossover, even on the 06
models. On the Dyna models for example you can hardly see them, but
there is a connection between the two mufflers.

Thank you, but it's getting autumn here :(

Hmm, there has never been a real summer this year here in Austria. The last
couple of days were the best days so far this year... :-(

It would take me a minute or two to find it in my book from Branch
Flowmetrics. They dyno'd with and with out the cross over. They plugged the
hole in the stock pipe. They believe that cross over is for, shit, now I got
to look! Quote from the book taken word for word, take it as you want to.
I'd be happy to scan it and email it to anyone who thinks different.
Next we removed the pipes and plugged the crossover tubes. This showed
almost no change at all in power, but would probably show up on an emissions
test as diluting the unburned gases somewhat.
Only thing I found the cross over tube to be good for is leaking and causing
a back fire on decel. I know of two bikes that had this issue.

Yep concur, I have owned HDs since 1970 all Sporties because they are fun
and you can modify the piss out of them.
My recent mod along with a Dyno run shows a net HP gain of 17 HP. I removed
the stock exhaust system cut off the x-over tube plugged and welded the
holes removed the chrome which blues any way and painted with 3000 degree
high temp black ceramic paint re installed the stock heat shields, drilled
out the stock exhaust baffle with an 1 1/4" hole saw, Made a set of tunable
baffles for the Dyno run, installed K&N high flow air filter drilled 4-3/4"
holes in back of the air box, installed a higher out put coil with stock
wires, rejetted the carb my total cost including the Dyno was less that
$200.00. It sounds great, runs like a raped ape and the best thing is I did
not spend the big bucks that the after market manufacturers tout you need to
make HP it is all bullshit. I was an engineer in the USCG and worked on
everything from gas turbines to pump engines we do not need any stinking
x-over and big $$ to make HP.

Great news. Mail it to Harley. Tell them they are idots and maybe they
will finally stop using the crossover.
What do they know about motorcycles anyway after 102 years of
experience? Tell them you found out that that crossover is just to annoy
us. Oh..and when you're at it send them that complete Branch Flowmetrics
Bible too. For it is a Holey Book. A book with many followers!
Disbelievers will be burned by a crossover!

Sarcasm will get you anywhere, the x-over is needed with stock HD systems it
does scavange and produce minimal HP but, it is old school HD should build
an exhaust with modern computer desigh just a throw back to the old days.

You need to pay more attention to what I posted and what I said before you
flame me for what was tested, and the results that were found. Your quick
wit to get bent was sure funny. After all Harley has already read the book!
I will post what was said in the beginning of the book. Then you can once
again take it as you want. And I bet I can already figure that out.
The following sheets and charts on the new Harley Davidson V-2 Engine are
the end results of over two months of all out dyno tests to arrive at the
spec.'s listed on these pages. The tests listed are the efforts of Harley
Davidson Motor Co. and Branch Flowmetrics to determined what changes could
be made to this engine to increase the power and performance without harming
the engines reliability and smoothness. Hundreds and hundreds of tests were
run on this program and we here at Branch Flowmetrics really have a great
respect for the Evolution engine design.
I've not yet found a published date on this book. It was a stock standard
1340 EV 80" FXRS used in the test. Once again I will be glad to scan this
page and send it to those who still don't believe it.
Now read again what I posted, and what the government wants, clean air.
Maybe this time you can understand it better?

Keeping it simple is always a good thing. I'm not out for numbers at the end
of a race track on a lighted sign that says I saved a split second.

I did. Can you quote me on what you posted about 'what the government
wants' in your previous post? I can't find it.
I will tell you why I reacted so sarcastic. You mention a book and to me
it seems you consider the people who wrote this as Messiases. You
mention the words 'They believe' and _you_ found out that it's only
causing backfiring and leaking. And now you wonder why I'm being
sarcastic? (you called it a flame).
Hard evidence is what I want to read. Facts from _independent_
resources. And not facts from a company that is owned by Mikuni (=Branch
Flowmetrics). Now _that_ is what you didn't mention in your previous
reaction and still don't in this last reaction.

Flowmetrics felt that the cross over would show up on an emissions test as
diluting the unburned gases somewhat. It is common knowledge as a government
standard for the clean air act to get the exhaust as clean as possible,
isn't it? Suppose that being one reason why Harley still uses the cross
over? At least on the TC88's they found a way to hide that ugly pipe!
Flowmetrics was the one who did the tests and stated it made little
difference in power you pointed sarcasm my way as if I did the test.
(Next we removed the pipes and plugged the crossover tubes. This
showed almost no change at all in power, but would probably show up
on an emissions test as diluting the unburned gases somewhat)
Seems very simple to me. They didn't brag on that cross over at all. I
posted word for word a fact that was tested with and with out the cross
over. You said you wanted hard facts isn't that hard facts? I didn't know I
had to say Harley was involved in the tests. Which I did in the reply.
Only thing I found the cross over tube to be good for is leaking and causing
a back fire on decel. NO I didn't dyno test with and with out the cross
over! I know of two bikes that had this issue. One was a Road King, we dealt
with the back fire by first looking at jetting. Finally using fogging oil in
the engine we found the exhaust leak at the cross over. A small build up
after lots of oil being sprayed, it showed the leak at the back pipe. Small
but mighty enough for the back fire. Leak fixed no more back fire. One was
on a Dyna Wide Glide. His too was found the same way. Leak fixed, no more
back fire. The leaks were fixed by new exhausts with no cross over. Sure is
funny no more back fire after the cross over's were removed so I stand by my
findings as a fact.
You got sarcastic enough for me to believe you were targeting me as posting
something that was false, yes I took it as flaming me. Jerry Branch had
nothing to gain with testing exhausts, but he did gain knowledge of his
heads. They had 4 different designs on this bike finding the right
combination to be what he still uses today.
Facts is what I read. And as stated Harley was part of these tests. How hard
of facts does it take. I offered to scan it. Maybe you could find the book
and read it. There is more in this book than stating that taking the cross
over wasn't that big of issue with a loss in power. And as I take it the
cross over is one way for Harley to keep trying to meet the demands of air
pollution control.
The book, Vol 2 $5.00, how old, I don't know. I got it from Sal. In the
conclusion it does say that the first book was published in late 1984.
The book covers many different mods to this bike. From cams to exhausts to
head design and carburetors.

Write them and tell them what you think I didn't right it. I answered a
question with facts taken by someone else with Harley's tec's being right
there too.
Once again I've said enough and its time to move on, the floor is yours.

almost, probably, somewhat...

No hard facts. Measurements. How many 'almost', how many 'probably'
etc...

That's no fact to me. An exhaust with a leak will backfire, with or
without a crossover.

Facts are what's being measured, not what people read or believe.

Ah! I see you waxed the floor.

'I didn't RIGHT it'? Well it's always better than mine, but my Dutch is
better than yours :)

Sure these were found at the cross over not the head pipe,
your turn to wax the floor.
