I found these on EBAY and was wondering if anybody had any experience or knowledge of this type of can.

It should also be noted that im not trying to build a GP bike im just trying to make a decent bike to take to a few track days. In other words im coming from more of a bang for your buck angle

A general rule of buying things is... You get what you pay for.

I think these cans may have been discussed a month or so ago in another thread.

Se habla Chinese?

Also, if you haven't heard it before, even the highest quality carbon cans don't last all that long on these bikes. So they "might" not last but I've never used them or know anyone that has.

Guess that makes you our guinea pig......

Let us know how they work.

Thats why I havent purchased them yet. Trying to find out if theyre gonna be any better than the stock cans i still have.

Why does carbon fiber not last long on these bikes. What is the preferred material on them

VTRsurfer

Carbon fiber is just that...fiber. It's constructed like fiberglass, a woven carbon mat is coated with resin. Heavy vibration, or an impact, can make it crack. Also very high heat will burn it.

I've heard of members who have had no problems with carbon fiber cans. But when I got mine I chose titanium, so as not to take a chance, since I ride over 12,000 miles per year since retiring.

Otherwise aluminum or stainless steel are good materials. Carbon fiber and titanium are the most expensive. That's why the low price for CF seems very questionable.

but I'm poor and run Aluminum cans......


As for the carbon cans, some folks have had good luck but I have seen a set of "name brand" carbon cans self destruct after a single season. It has to do with the large exhaust pulses flexing the can unlike an I4 which has a more constant pressure, so no flexing.

VTRsurfer

Yeah, but I got my titanium cans courtesy of the insurance company of the 19 year old who rear ended me at a red light last March.

Now that's the way to do it

Those have been on ebay for a long time. I wonder if they've ever sold any. I shy'ed away.

Good point about the pulsing. This is the first v twin sportbike ive owned, all my others are I4s so i didnt even think about that.
Yeah unless i find a hell of a deal on some used titanium cans im starting to lean towards good ol aluminum

Welds look nice and they will save you weight. You hear a lot of detractors when it comes to carbon exhaust on our bikes, but after a quick search I couldn't find any specific posts concerning a set actually failing. (I have TBR carbon cans on my bike so fingers crossed.)For a track bike I would say go for it and report back with your experience. Or look out for a used set.
On a side note has anyone realized any actual (dyno results) gains from their slip ons.

Carbon cans fail when the packing blows out and the owner does nothing to maintain the units. Aluminum and titanium have the heat resistance to put up with this negligence.

Good info in that article.
I do wonder on the CF pipes if the CF is layed thicker on the name brand companys

Tweety

That's the titanium one's... A good bit different to the CF one's... Just saying...

Doubt it's much different... It's more important whats inside...

Many use a thin metal sleeve inside the CF, but not all... Then there is a lot of differences in what packing material is used, and if it will burn once hot enough...

For the price I decided to try'em out on my bike...

YouTube - SuperHawk w/ Danmoto GP style exhaust installed

So far I'm pretty pleased. If you order them don't forget the baffles, just in case you decide to run with them installed it is quite loud.

dang, they are tiny!

In looking at the actual DanMoto site, I believe you can request them to make the can longer.
