i installed a pair of 2 brothers slips on my friends 2010 Z 1000 last night. it took about 1 HR. dealing with the servo cables on the right side was the only hard part. they sound and look good. i hate to remove those servo cables. kawasaki spent a lot of money putting those on the bike to help mid range power. i hope it still has good mid range PUNCH with that removed.

I was wondering if you put any type of fuel mapping device on it?
Because the bikes factory set up is lean of the optimal stoich setting.
Becareful because you could do alot of damage if the bike is run in a lean condition!
I was advised by the mech.at my dealership to put a juice box or similar device on my factory set up bike because the bike is already lean from the factory.

the fueling is RICH in WOT to protect the engine. i have never seen a pipe cause a bike to be too lean under full power. air box mods can drive fueling crazy.
i also installed a MUZZY full system on my own stock 04 Z 1000. no problem.
a few years back i had a stock ZRX i installed a muzzy and did a dyno pull to check the fueling. it was almost spot on.
a lot of bikes run a little richer at low engine load after replacing the stock mufflers and cats, but stock most bikes are lean for smog reasons at low engine loads. i am not a big fan of piggy back [ PC 3 etc] computer aids. get the bike on a dyno and find out how the AF ratio is before you do a PC. yes you might need one. a PC only gives you the ability to change AF ratio.if you do not need it why spend the money . un needed electronics are never a good thing. i am going to dyno my 04 z 1000. if the AF ratio is close i will not put a PC on it. if it needs it i will.
just my 2 cents. flame away.

Can you take a video of how it sounds? I'd really like to hear how much better it sounds with the slip ons.

Im beginning to wonder if these dealers are getting kickbacks from the manufacturers of Power Commanders...

My dealership told me the same thing: OMG, dont put slip-ons on without putting on a power commander!!! We can sell you one for $465!

Several others I have spoken to, including custom bike builders, have told me that these things are fuel injected - and the PC has to adjust for differences in altitude - when the fuel mixture slightly leans out. Installing exhaust pipes only will only slightly lean out the mixture - and the PC will adjust itself for it.

Now, if you go opening the airbox up, or installing a freer flowing air filter, the mixture gets WAYYYYY leaner, causing the NEED for a power commander.

But with just slip-ons, you are fine without a power commander.

Ive got m4 slip-ons on my 2010, and I notice no drop in power or other issues. Cant even tell the exhaust valve was removed.

I have just bought a set of Campbell sidewinder slip ons, I plan to install them this weekend but have no idea what I am doing with the valve cables. I understand I have to disconnect them from the power servo but this will leave the servo exposed and the exhausts are not supplied with a cover. What should I do, any ideas

You're over-thinking it, bro.

Loosen the right side muffler, then turn it so you can get at the cables. I had to use a pair of needle nose pliers to open the valve up so that it created slack in the cable line. Removed the cables from the muffler. Then, under the seat, you simply unclip the black metal clip holding the cables in, then unhook the cables at that point - you will notice that the servo is already exposed! All youre doing is disconnecting the cables... Once both are disconnected from both ends, slide them out from behind the frame downtube. Then, install the slip-ons!

Took me less than half an hour to install my M4's...

the servo cover is under the seat. all you do is remove the cover, remove the 2 cables and re install the cover. end of story. kawa got cute and used one of those torque drive tools for the bolt with a pin in the middle. i had to use a hammer and punch to remove and re install the bolt[ it worked fine]. the stock under belly muffler [ cat] kills a lot of noise. even with the 2 bros slips it is not very loud,. so if you want LOUD get a full system.
i hate how newer bikes have those ugly under belly mufflers[ thank you EPA] it is one more reason i like the pureness of my 04.

just leave the cables on the stock muffler, why remove the cables on both ends ?
You need some slack in the cable line before you can get it to come out...removing the cables at the muffler made it a hell of a lot easier to get the cables off the servo.

Thanks for the heads up on leaving the cable on the muffler.

Not sure about the states but in the uk we have to put our bikes through an MOT annually, Have a feeling my new cans will fail based on Decibel level. My understanding is that the servo and cables allows for compression to build up if the engine is cold??? There is a point coming, if I had to re-attach the stock cans for the MOT could I leave of the the servo dis-connected for ease of transfer with out this causing a problem?

take the servo cover off,remove the cables. re install the cover. pull the cables threw the gap in the frame. leave the cables on the right muffler. for inspection i think you could re install the stock system in about 1 HR.
i am not saying removing the cables from the muffler is a bad idea, it just was not necessary in my case.

Exactly. I don't have that much knowledge working on bikes and I definitely want to switch up the exhaust if I can. A video would be a great help.

I removed the cables from my 2010 and did not notice any difference in performance. I just removed the cables from both ends and pulled them out.
