Hi chaps, what do you think, Ackro slip-on, Full Akro, or Full Yoshimura? I have read somewere you have to remove the full Akropovic to change the oil filter, Is this true? If so I think that rules it out.. Anyway whats your thoughts?

both r good choises and i would go full exhaust on either thats for sure

If you can afford the Full System...get the Akrapovic. My brother has the full system on his 954...sounds so sweet, plus it comes with some substantial power increase, who can complain?

Full System- more work, more power, more money
Slip on- less work, less power, less money

You choose

Goodluck with whatever you may decide to do.

Akrapovich and Yosh aren't even in the same league. The Akra's are VERY nice.

If you look on Akropovics web site and compare the difference in HP gains between a full system and the slip on you will see a tiny gain between both.Ignore their stated RWHP as they are shall we say optimistic.I would save your hard earnt a go for the slip on.As for the full system interfering with the oil filter removal,i had a quick look at mine and couldn't decide as the filter is a strange shape.

I'm thinkin of a Akra slip on myself, looks better than the pice of junk that comes with the bike. No way can I afford the full system.

Does this Akra effect the exasust system adversly?? What happens to the valves on the standard system?

The valves stay with the outgoing original silencer and after the fitting and programing of a PC111 you should notice a def improvement in low to mid RPM.And what a lovely noise it makes too.

And it is a shame that Akro dont do those infill panels but was wondering if the Yoshi ones would fit though.

I saw a guy on *********** with a akro and the yosh heat shield but I have yet to hear back from him on how he did it.

You mean, round?

Since the valve is in the exhaust, it is no longer used. You will need to keep the servo connected though.

You can use the Yosh and their panel doesn't work with their exhausts either; unless it was produced in middle November.

Probably some bending and cutting on the panel.
