View Full Version : Yoshimura Can
Hi, I'm thinking of getting a yoshimura exhaust can for my sv650 k3. Does any one know of any links so i can hear one in action ? The main reason for getting it is too be heard when filtering in traffic as the standard exhaust is so quiet.
Thanks.

Youtube (.com) has lots of links for different Yoshi cans, on different bikes.
Sound quality isn't great usually though.(on youtube...yoshi' sound great)
Best to hear them 'in the flesh'. Law's sounded great and Nick_1871's nearly made my ears bleed when i followed him through a tunnel. That was enough for me to order a TRC carbon.

Has it arrived yet? :)

Haggis has a yoshi on his curvy SV, sounds lovely... Plus, they have the best logo in biking :) But it's always seemed like their SV cans are a bit of a token effort, the systems are pretty heavy and don't make good power compared to Arrow or Leo Vince.
Went for full Yoshi system. Sounds fantastic. V-twins and aftermarket cans are matches made in heaven. I dunno about other makes, but the TRS makes the SV sound like a MotoGP bike; especially when it is puttering under load. Would be surprised if they're not any good. They are after all partners with Suzuki and uses Suzuki bikes as their testbeds. Going for a dyno session next week, so I'll let you guys know if there's a power hike. What i can say is this; the power delivary is much smoother and linear as it should. The engine is also more free revving. The engine brake also doesn't cut in so much, allowing one to hold the lower gears while cornering and powering out smoothly. All these makes the bike handle much better and make full advantage of the responsive chassis. Its this accessible, every day performance that makes the upgrade pay for itself.
As for the noise. Well, let's say I am never going for an inline 4, ever!

Got mine off ebay although it wasn't SV specific - not sure there ever was a Yoshi for the curvy?
Bit of crash damage so i stubbied it and fitted a new inlet cap. Does the job!:cool:
Agree about the weight, no real saving over the stock endcan i lobbed off.
Are there any different in weight on the carbon/titanium vs the stainless steel?
I'm thinking about the full TRS system (in stainless steel), for my black pointy.
good question. i just thought its the finishing. I was advised that Titanium is a worthwhile upgrade from Stainless Steel. Perhaps looks and weight. But an extra £50-60 for carbon maybe not. Given the black rear wheel, and that your bike is black, maybe a carbon can may not standout as much?

I've ordered a TRC carbon.
Which looks like this:

The older version looks like this:

The main difference is apparently less weight, the newer version dissipates heat better, and it generates more power apparently.
I wasn't a fan of carbon exhausts but i'v really come around to them looking amazing on black bikes. However on any other coloured bike i would have a titanium can.
whatever you do, you MUST remove the baffle ;) O, i presume you are going for a PCIII with dyno?
It stands between the stainless muffler, and the carbon. I don't fancy the titanium..
If you ment me, I'll try to get the ECU remapped, along with a new airfilter/powerfilter (any recommendations?).
Mentioned this is the ECU thread. Spoke to a dyno tuner centre. According to him, ECU remapping by a Yoshi box only shifts the mapping curve left or right. So its not optimised for particular systems, much less set ups. PCIII changes the ignition curve and allows for finer tuning. So is recommended. Many were saying it doesn't make much difference. Well, after upgrading, while waiting for a full dyno tune up, I switch the mapping to one for a full Micron system. Compared to the stock map i was using previously, i think its not as smooth. If you're going for a full system, go for a full tuning. Well, I'll let you know on Monday if its money well spent. but i feel something missing.
As for air filters, its between K&N and BMC. The latter is £5 more, but is thought to be a better product. if its the difference between a few more months of life and 1-2bhp, then i think its £5 well spent.

and it is about 20 lbs lighter

Do you have any idea if the stainless steel is the same weight, or heavier?

I've got a CCC (Carcon Can Company) on mine. Road legal and sounds really nice and very affordable.
Really though, if it's about being heard filtering it normally too late by the time any caggie can hear even the loudest can. I mean after all normal filtering is at relatively low speed and they'll only hear you when you're next to them (hence too late).
Anyway get your can or full system and welcome to the org :D
IMHO, the can is to "alert" ditzy female pedestrians dashing across the road ;). unlike in-line 4s which are described as screaming, V-twins give a little "ahem", like clearing one's throat. Surely that is more polite and discreet as befitting treatment to the fairer sex.

The titanium or carbon are significanty lighter than the stock can, where as stainless is still lighter, but less so than the aforementioned.

It's not a huge difference though, when you feel the sleeves by themselves stainlses is a bit heavier, but not enough to lose sleep over unless you're aggressively shedding weight. Remember that with most cans the end caps and inner core will be stainless anyway, so we're talking about a small part of the total mass of the can.
Stainless has its advantages, as it's harder wearing, and you can polish marks out of it pretty easily. It's heavier, but not terribly so.
Carbon fibre tends to go dull and cloudy over time (particularily since bike carbon fibre tends to be pretty low grade) and can crack or vibrate to bits over time, plus if the exhaust ever runs too low on packing the carbon fibre is liklely to burn through. Some bike cans advertised as carbon are actually a thin overlay of carbon over steel or aluminium, though that doesn't seem to be so common now.
Titanium's a good option though, it's light and strong, and doesn't really corrode or degrade. If you damage it, it's hard to fix- it's difficult to match the original finish and it's hard to work- and if it overheats (like with carbon) it can discolour- but it won't fall in half like carbon can in those cases. Vibrations can crack it though (see: Blue Flame, and my exhaust)
I'm well bored at work today. Can you tell?

Agreed Northwind, in reality other factors such as rider weight, will make much more of a difference.
Have to admit, went for the Titanium more for cosmetic reasons. I use a 52L top box most of the time and lug some spare gear everywhere. I know where i need to shed some weight!
went for dyno-tuning today. Gained 4bhp on the rear wheel to 72bhp. Already mapped PCIII to full micron system. So probably got 6-7bhp gain at the rear wheel for changing to a full Yoshi system and BMC filter. The downloadable Micron system curve is not a bad optimisation in itself. The dyno session just shifted it up by 4bhp across the board. Improves the idling and low rpm definitely.
PCIII does not optimise for power, rather it optimises for fuel-air ratio. Which they theorise will bring performance gains. The forum here suggest it may not be the best method, but it certianly should be the most efficient combustion. So at least i can claim eco credits for spending the money ;)
Is it worth the money? well, again its up to the individual. Its one thing to like lobsters. For some, they dun care how its prepared as long as its lobster being served. Others will be prepared to fork out a little more (either money, effort, or both) to have it properly cooked so as to extract out the very last ounce of flavour and enjoyment.
not to mention, food when properly prepared and cooked, can taste fantastic even if the ingredients may not cost much.
I ended up getting the s/s yoshi fitted on saturday just gone and am very happy with the sound. baffle's are still fitted. (for the time being)
