Slip-on & exhaust valve

When installing a slip-on exhaust on an 06 CBR1000RR do I lose the exhaust valve? What's the impact on low-mid range performance? I'm looking at a Jardine slip on for my bike.

Thanks.

Re: Slip-on & exhaust valve

With a slip on or half system, you keep the exhaust valve. With a full system install, you loose the exhaust valve. The bennifets to not having an exhaust valve are more HP at the top end, one less thing to adjust, less weight, and sometimes they rattle. The HTEV does provide backpressure at low rpms wich increases torque at slow speeds. Usualy, if you get a full system, and drop down a tooth in the front sprocket, you wont notice the slight power loss at arround 3K rpm.

Re: Slip-on & exhaust valve

nope
you lose the exhaust valve with slip ons as well
you are thinking bolt on systems where only the can is replaced.
with a slip on the pipe is also replaced.
on the 06 the servo for the cables is below the rider seat in the same black plasic box as the trunk release. that valve is mainly there for noise control
and will not affect performance when it is gone

Ok, I was speaking from experience on my 954, the 1KRR is set up differently.

Re: Slip-on & exhaust valve

Yeah, that checks. I looked the bike over last night and saw the valve assembly. The new two-outlet Jardine looks fuggin sick, so I'm going to have to get one.

Thanks for the replies.

Re: Slip-on & exhaust valve

I have just fitted the Twin Jardine Carbon slip on onto my 06 1K, confirm remove ex valve and the cables, I experienced FI fault light until I completley removed the cables, I little fiddley but once removed the cables, and servo was back in correct position FI fault gone. Take care as the servo gears are not that robust. DONT PULL AND TUG. Located just behind rear key box, not as stated with the Jardine kit.
Cheers

Re: Slip-on & exhaust valve

remember 04/05 the servo is by the motor
06/07 the servo is inside the same black plastic box as the trunk release

Re: Slip-on & exhaust valve

Anyone know which wire is cut or jumped to stop the FI light when removing the servo on a 06 1000?

The valve is for emissions. To do it properly, you should have a Power Commander to richen the mixture. The length of the exhaust supplies plenty of back pressure.
