View Full Version : single can on m600?

well got my monster, but its a bit lacking in the noise/power department,

I'm assuming that swapping the two restrictive "3 chamber" cans will give a nice increase in pick up and much more satisfying noise.

after looking on youtube I quite like the sound of single cans on a 'twin.

is there any reason I shouldnt do this and stick to twins?

I was planning to visit a "specialist" and get one made up from the exhaust holes back. or is there a "proper" one available?

QD Maxcone, or SC Project do single cans for the more recent bikes, it may be worth checking with them?

so will a single can effect performance?

Well put it this way, mine gained an extra 6hp after fitting one. :thumbsup:

How long is a piece of string? Giler's 900 looked great but lost about the same. Too many factors to just say yes or no... definitely maybe

Remus make one for the S*R bikes. It will loose some weight but I think twin cans always look better

Keep an eye out for 600SS exhausts

They had a 2-1 as standard - but you may need to swap footpegs to match

Otherwise it wouldn't be that hard or expensive to get a custom one made up

General Vincents on other monster forums is that they seem to lose power, not something you want to be doing on a 600 ;)

Then again, I was told that a few DD racers use single can systems.
You might struggle to find decent 600ss headers as I think they were all plain steel and likely to be well rotten by now.
Its worth remembering that the std monster system exhausts through both cans simultaneously, so a single can has a lot more to handle.
I guess that also means the std cans aren't as restrictive as you might think, because you effectively have two connected in parallel, giving twice the outlet area.
Personally though, I like the simplicity of a single can and I like the unbalanced look too...and it does save the weight of one whole can, as well as making access easier.
I was seriously considering one myself, until I was offered some cheap hi-level termis.
Some say that the increased pulse pressure could tend to blow the can apart (Chris Dabbs...? mcn)
All things considered, I reckoned that if I got a nice large bore, free flowing can, with a large inlet dia to accept a big bore collector, fixed in the chosen position on the bike, it would then be a simple matter to cut up a spare set of headers and marry them to the can with a suitable collector, aiming to keep both headers of similar length.
Whether it would be possible to adequately calm the noise from the single, free flowing can is an entirely different matter though. ...I thought it unlikely.
One thing I did discover with the termis is that the bike responded much better from low revs.
Obviously the reduced restriction may have helped, but I kinda fancy that the extra length due to the extension pipes might have had a lot to do with it.
Certainly, any attempts I had made at a rudimentary calculation had suggested that longer systems work better at low revs.
In light of this, you might consider a longer, single can system while you're at it. (I guess that means a hi-level).
The extra length can only help in the silencing department too, I guess.
For what its worth, those are my considered thoughts on the idea.
I do have some engineering background, but this is all just partially informed guesswork really.
Kato made an interesting post on exhaust design some months ago...sorry, I can't do links.
The other thing of course is ground clearance, which is said to be lacking in the std system.
I began, like you, in the search for a little more noise most of all.....I just couldn't hear the engine at all above trundling speeds and it was affecting my control/feedback.
In the end, my unbaffled termis are a little too noisy, and that can be just as annoying, particularly if you do have some social conscience. I only mention this to caution you against spending a lot of cash on a custom system which turns out to be too loud.....the pressure is on for that to happen in a single can system, I think. And retrofitting baffles will only add to the high pressures in the can.
I'd say do it, but try to cover as many problem areas as you can. Its obviously more feasible on the 600 than the bigger motors....Ducati themselves seem to think that too (600ss).
....but then again I think someone on here was offering cheap hi-level termis too.
One other thing...some say that the "crucifix" section of the std headers is not actually as restrictive as it looks. (and hence the hi-termis drop straight on and work reasonably well).

The weekender would be a good place to listen to a few other monsters with various systems....??

Oh...and I guess you would need to budget for a dyno session to adjust the fuelling to suit a homemade system, particularly with the fairly major change to a single can design.
Its probably a good idea anyway, but I haven't bothered yet cos it seems to run fine....with the termis.
(no...I'm not on a commission).
Hope some of that helps.
