Hey all

I'm was about to order some Titanium slip ons, but they are back ordered for 2-3 weeks. The carbon fiber ones are available.

I've read on here something about the carbon fiber not being good with twins. Is that true? Why is that? If it's a heat issue, can't the titanium ones have similar issues? I've searched on the forums a bit and can't find my answer. Probably there, but I can't seem to find it.

I loved my CF slip ons on my VFR. If there's truely an issue with CF, than I'll wait the couple weeks. If not, then I'm grabbing the CF ones now.

Thanks
Tim

 

The 2bros carbons are some of the best (the Akro's suck for big twins) but even titanium can have issues; and both don't do well even in minor tip-overs. Carbon does not hold up well under the heat (especially the right can) and the big puffs a VTR huffs. If your'e looking for looks then yeh carbon and lesser so, titanium is the ****. But if you want function over form, then go with the good old aluminum 2bros slip-ons (preferably used) and spend the leftover dosh on SS brake lines and fork springs, plus have gas money for at least the rest of the month.

 

FWIW, I've had Devil C/F cans for 12k miles now and not a single issue.

 

Thanks for that.

A couple issues that went into deciding on the 2 bros was that I love the sound of them, and that I could get the sound suppressor tips for the new M5 model. I also wanted standard mount (not high mount). Normally, I'd never get those tips, but I live in a 10 unit condo building with some (trying to be polite) older people who don't like the noise of my bike as it is with the stock set up. From what I can tell the older aluminum pipes are much louder than the new ones.

I'm also getting new springs. Now trying to get the dealer to understand that I want them to install new springs into the current shocks, not sell me $1k shock for the rear etc. has been a challenge.

It's good to hear that the CF has lasted for some. I tend to put 6k or so on a year. I'll probably just plan on repacking them every 2 yrs and go with the CF.

Thanks

 

I absolutaly love the carbon cans, they look freaking awesome. I get more compliments with the carbon cans. The sound is amazing, turns heads like crazy. Also makes the other sport bike riders really confused, they dont expect the pounding exhaust notes.
My buddy just installed the titanium cans on his rc51 and they look ok, but i definately love th cf look

Big +1 from me

 

Wuh??? The new maybe quieter than the old cans but the also "stock" cans?

I don't think so!

And where did the "shocks" come in? "Springs", as in plural? Do you mean forks too. Cuz we only have ONE shock and shock spring and TWO fork tubes and fork springs.

 

Carbon Carbon Carbon!!! The look awesome too and disperse the heat faster.

 

Me and carbon go waaay back to 1976. Whereas carbon composite material and manufacturing technology has advanced over the last 32 years, carbon was first and foremost intended for unidirectional load resistance at minimum weight. Its lightness is really lost on a road bike and while it does seem to disperse heat faster, it will still get as hot as any other comparable thickness material. And no carbon composite today has a binder matrix that sustains elevated temperatures without compromising strength due to heat induced degradation. When we designed the MAM structure (Manipulaor Arm Boom deployed from the boron-aluminum composite tube (autoclave fused on a mandrel with titanium male-female clevis's bonded to each end) space frame Payload Bay on the Space Shuttles), we actually sheathed over the carbon MAB tubes with kevlar skinned, phenolic resin impregnated kraft paper honeycomb core "bumpers" for impact protection. However, the MAB tubes (from 10 to 16 inches in diameter) could not support their weight in Earth gravity and were kept in cradles until in orbit. We (Convair) also did not use rivets to attach the shoulder, elbow and wrist made by SPAR Canada. Instead, we bonded machined from hogout titanium end rings to which the shoulder, elbow and wrist were bolted (with titanium fasteners of course). The attachment rings extended well into the carbon tubes.

The attachment of cf cans to the metal exhaust components is a weak link IMO. Look how the MotoGP cf is done, and you'll see the difference to what is available for street bikes. And often they run titanium cans.
