Never mind.  If i had been a little patient and research a little. I would now a fuel injection tunner of some sort is the best way to go with an after market exhaust.

Although it doesn't hurt. If your only using a slip on canister. Then a fuel processor is not really necessary. Although if going with a full exhaust, yes you should use one.

Are you speaking from experianc Capt Bob.  I have added cans to my other road bikes and it created a lean hesitation in the throttle.

   Yes. It has been discussed many times before. I also spoke with one of the aftermarket tuners (who sells both the power commanders and both full and slip on exhausts) about this.  He has performed dynamometer runs on all of this. He confirmed that you will not need a PC with just a slip on. But he would be more than happy to sell me a power commander (with the appropriate mapping) if I wanted. But he again told me that it wasn't necessary. Although I did purchase a PC V with his mapping, from him when I removed the secondary buttery valves from the throttle bodies.

I put a 08 ZX exhaust header with out Cats (cut collector removed them) dual Two Brothers mufflers and there is NO problem . I can tell after 4,000 it really turns on.  :beerchug:

You got to get those puppies out (CATS)  for it to BREATH , old story it you can't $hit you can't eat.

What is the weight savings from switching to an aftermarket slip on? Any Idea what the stock one weighs vs aftermarket?
I am interested in the weight savings but not really needing to tweek the fueling. Anyone know if there is a better slip on for not having to buy into the whole "Power Commander"/remapping game?

I guess If I wanted a  lighter bike, I could drop 30 pounds...but I know how likely it is for that to happen!

Thanks Moose

From what I understand most aftermarket can's are about 20lbs lighter then stock....but honestly, if your only goal is weight savings then I recommend saving your $.   You are dealing with an almost 700lb bike,  and unless you are racing, dropping the 30lbs won't make a realistic difference IMHO
