Exhaust Gains
I've been looking at some replacement cans for a while now. To be honest I was all set to order the X-Racing single can system, but after nearly 2 weeks I'm still waiting for the guy to answer my questions, and they aren't difficult one either!
What I'm looking for, rather than a power increase, is weight reduction. Has anyone put their cans on the scales at all?? The original ones come in at around 8Kg, so it shouldn't be difficult to get some inprovement on that. Akrapovics I understand to save arounf 0.8Kg so the �1K price tag just isn't justifiable. I'm considering the Arrow or LeoVince twin pipe setup basically becasue of the price. I think the best solution would be the single system from OTR, but again this is expensive.... Anyone got any stats on these pipes ? I'd be happy with some increase in mid range torque, rather than HP....... :newspaper: |
Well I've just sold my Leo's, so you missed a chance there ;) Weight wise they offered little saving I felt. Having had them on my Capo I knew they were heavy silencers before ordering.
As I said to you at Dent, the Tenere seems to be a very loud single, I dont know why, it just is. Maybe with more time and inclination I'd look at making headers and staggering the join to try and change the soundwaves/pulses. I've got something in the pipeline (no pun intended) at the moment for a single silencer, will see if it comes off. When I had the Tenere on the dyno with uncorked Leos it registered 47.74 rwhp, but was running lean. The consensus was that with the stoichiometric levels addressed I could have been around 50rwhp. This ties in with previous dyno results here. Torque wasn't measured sadly, but I have my baseline for experimenting with. |

The akro's fitted to my ten were alot lighter than the standard cans, and i know the leo's Bigb fitted were around the same weight, allthough sound alot nicer...

They are about 7kg, you will get LOADS more bottom end grunt :glasses2: |
I have personally lifted them both independently. The OTR feels signficantly lighter, more than 1kg. In addition, straight from horses mouth, it weighs 4.2kg. Hope it helps.

That's half the weight! Still nothing close to the X-Racing gain of 6Kg's though. How hard can it be to make a can that conforms to the law..... |
But, why would you like to decrease weight?
I'm not having any problems and i'm just 80kg, 1.78m. My bike is also just 25kw, so around 30hp. |

4.2kg for the OTR I believe is with the Cat, whereas I think I read it somewhere that the X-racing is without Cat, correct? Double check with Thorsten at OTR once you are getting more interested in his. |
For lightness I think you are going to have to go for titanium, CF (not so great on singles) or Ally, and one silencer is definitely the way forward, obviously.
I'm pretty sure the second silencer on the Leo's is there for visual balance; the link to it is as a strange angle not conducive to good gas flow, and the pipe is a narrower bore than the primary link pipe. For reference, this straight through, same as the Leo's, Remus pipe weighs 1400grammes. http://i97.photobucket.com/albums/l2...ikes/remus.jpg That's a lightweight pipe. |
