I have a 2003 CBR 954 RR that is stock except for a Yoshi slip on. I want to change the whole exhaust out and add a power commander for better performance any ideas out there? Thanks

Ideas regarding what exactly - how to do it?

 

[Go410s]

Ideas on what products to buy for the best possible match-up for the upgrade. Guess I should have been more clear on the question for recommendations.

Well, my only interests are weight loss and power gain - I don't care about looks or sound. For that I'd go with something high-end in full titanium - Akrapovic, Arata, Sato, TiForce, Arrow and the like are good.
You said you have a slip-on but do you mean a bolt-on or a slip-on with a mid-pipe? If it is then you _might_ be able to get just the Yosh header and use your muffler on that. If it's a bolt-on I don't know of any aftermarket headers that take a bolt-on muffler.
I don't know what you mean by match-up since you said it's all stock and you're only fitting an exhaust system. What do you want it to match up with?
The PC3 is purely for tuning whatever modifications you make to the engine.

I am willing to do motor work too, for more power. I just don't really know where to start. I've been told that exhaust, PC3, intake and engine modifications (didn't specify exactly what engine modifications), are the way to go but I wanted to get your opinions, I think the guy telling me this trash, is trying to set me up for failure and cause damage to my bike (he is a pure cruiser guy). So any information is a plus for me thanks.

Okay.
First, what sort of power are you chasing and what's it to be used for?
A full race exhaust system will give you the biggest single increase in peak power although you'll probably lose some midrange.
The PC3 will allow you to regain as much of the losses as possible though.
A set of race cams would probably give you the next biggest gain.
520 chain and lightweight sprockets are good bang for buck.
After that it becomes much more expensive for each additional hp.
Probably the best would be magnesium or carbon wheels as you gain power as well as improve the suspension, braking and steering of the bike.

I dont really know what power I am chasing I do want to be able to take it to the track once in awhile and still be able to ride it on the street every day too. Right now I would say I would like more mid to top end power, for now.
The bike is my preferred daily rider (besides my cruiser). I've read that going -1 on the front sprocket is a good upgrade to reach that mid to top increase. But I've never worked on bikes before either. I have worked on cars though (I know bikes are different).

If you haven't been riding long then I wouldn't waste your money chasing power. Spend your money on track time and learning to ride - that'll let you ride a _lot_ faster than any power gains will.
Dropping a front tooth makes for a more enjoyable bike but it doesn't give you any more power.

I appreciate the information. I've been riding street bikes for about 7 years and I never did any upgrades on them before. That's why its new to me in that aspect.

I have been wanting to get on the track to play around more since it is a lot safer than the streets. Thanks.

All you need to keep in mind is that power does not win races. At some tracks 120hp 600cc Supersport bikes lap faster than the 200hp 1000cc Superbikes

Yep I agree. Learn to ride the bike to it's full potential before worrying about adding more power than you can effectively use. Look at the 'Busa. Sure it can go fast in a straight line, but what's the point. Sportbikes are meant to be driven hard and fast in any circumstance.

I know on my blade I would be more interested in dropping weight than adding HP at this point I think.

never should have ridden my buddys 600rr. makes my bike feel soo heavy

Reducing weight is the first thing I do when I get a bike. Everything that isn't required comes off and everything that is required gets lightened or replaced with something that is lighter.

Thanks everyone for the advice! What are some of the things I could do to reduce the weight?

if its a street bike mostly just stick to the simple mods, full system, pc3, filter, gearing, and maybe aftermarket velocity stacks like factory pro...

 

[sscottab]

I would recomend upgrading the suspension first, redo the forks and rear shock also add a damper, then look at the power upgrades.

 

[Go410s]

I picked up a Scotts damper. If I change out the full exhaust do I need to have the computer flashed for the air to fuel ratio?

You probably won't _need_ to but it's likely you would prefer to get a PC3 to smooth out the power.
You can't "flash" many bikes.
