I did a search and just found a whole bunch of people saying don't do it. I'm trying to find the why not to do it part...
Not that I am running straight pipes on my bike, but I want to do something until I get rid of my current cans and buy the new system I'm saving up for.
I also see when I searched Google, that lots of people seem to run with little to no cans on youtube and different forums.
you will loose torque and most likely you will have a headache after a shiort ride. Plus if there is to little Backpressure you could potentially burn up the exhaust valves.
If you don't care about powerband effects in the short term, and you don't care about pissing people off and harming your own hearing unless you use decent protection, than you could do it. It will not send a good message to the cars you more often than not come across and it is certainly not cool, but you would not be the first or last. This is not intended to put you down like stretching a swingarm or something but many view it as similar intent
As for your motor you likely won't harm it. The header alone adds enough pressure that the valves won't be affected. Ive worked on a number of bikes with the Boz systems and had one on a 2006 ZX10R for a good deal of time. No mechanical issues; but it will drop some low and mid range power; but have a high peak power. And yea it will be loud as hell!
For the love of God! Please don't squid out your rc. Save your change and buy a real exhaust or something, but straight pipes are for the attention whores.
Plus if there is to little Backpressure you could potentially burn up the exhaust valves.
That is completely false. The only way you would burn up the valves is if you ran it with no header attached at all. The backpressure thing is a MYTH !!! Any internal combustion engine running open headers is going to make more power then the same engine running headers and a muffler. It has been proven time and time again.
Now back to the op. I would advise against it. For one like the others said all your going to do is piss alot of people off and go deaf in the process. Now running a gp setup like a bunch of others on here are doing including myself I dont think there is an issue. Its still alittle loud but it looks alot better IMO. With the right mapping your bike will run just as well as a more expensive bulky setup.
I like my exhaust loud but running without the muffler is obnoxious and painfully loud. I lost one of my the bands holding my sato pipes on and removed the muffler long enough to go to the hardware store. If that is the sound harley riders deal with on a normal basis I wouldn't be able to handle it.

I have to correct you on this one, a CORRECTLY designed header will produce MORE POWER thruout the powerband INCLUDING "top end" than straight pipes. A properly designed system will use pressure waves to scavenge flow and increase power. A close friend does design work for Leo Vince (among others) and runs into this mis-information all the time.
Semper Fi!

PS. before you run open pipes, watch the "F-word" episode on South Park, you may change your mind!

Don't most of us turf the rear seat and pegs soon after we buy em? I know I sure did. I don't share my bitch with no one I hope you're lucky enough to feel the same way some day!

to say it's loud is an understatement. to say it's obnoxious is putting it mildly.
it won't harm a thing mechanically.
I rode mine straight home from the stealership and proceeded to remove the passenger pegs and install the banzais the rear seat has never even been clipped on, ever. nor will it ever be. now that I think about it, there has never been any foreign ass on my seat at all. I'll save to two up for the vfr.

Rocky what exactly are you correcting me on??? A "correctly" designed header minus a can is considered "straight pipe". I dont think the op meant the shape(straight)of the pipe.
what he's saying is that if you take a system that is designed with the cans on it for the most power it is tuned with specific length, diameters and volume. so what you said is not true. ie if you take said system that has a length tuned to maximize scavenging and anti-reversion, and then remove some of that "tuned" capacity you have effectively negated the benefits of the system design and will lose power. it might sound faster, but most of the time it isn't.
a side note: straight through mufflers; like most non factory bike mufflers, flow just as much as a piece of straight pipe. and depending on the design of the louvers can actually flow more by creating micro turbulence along the wall which helps to increase velocity. which in turn helps with scavenging and creates more power. so the can vs no can argument is really a moot point, and you should be thinking more about things like optimum length and diameter
Get a brain...and shut your bike TFU. It's idiots like you that make us loose our rights.

Are you serious? I come here asking for advise and this is what I get? Thanks to everyone else for helping me, but get a clue guy. You wanna call me a squid when you don't even know me? Never ridden with me?
running straight pipes?
I hope you're lucky enough to feel the same way some day!
