Default Will bike run good without an exhaust?

I'm tired of looking at the ugly stock can on my bike. I also want a louder exhaust sound but I can't afford a slip on right now. What would happen if I just took my can off and ran the bike like that?

I don't think that's even legal.. Dunno might depend on state laws.

Hell, I saved 14 pounds by ditching the entire exhaust. I mean, yeah, it's a little loud...185dB, and my exhaust valve timing is way off, but I duct-taped some chicken wire onto the open ports to keep the sugar gliders out, and now it only stutters most of the time. Then all I had to do was put tin foil around the front wheel, the forks, the fender, the upper cowl, and the radiator (whew, hot!), so the fumes won't turn them all black. I swear, mufflers and especially header pipes are just another way for big corporations to keep the little guy down. Live free or die!

Exhausts are designed to run at a specific length (tuned length) - You'd probably burn valves.....not a good thing.[X(]

All engines are designed to run with a certain amount of back pressure - the trick is to get the pipe to the point where it goes blue, then cut it off 1/2 inch before the bluing (or is it after) - problem on a bike is, you'd need a looong pipe that would stick out way behind the rear fender.
GP bikes don't use silencers, and run at 130 odd decibels, but they have specially designed systems.
You'll burn valves, insufficient back pressure. - I wouldn't do it - rather find a cheap can built for a bike of your bike's cc, and fit that - much cheaper, and may give you the sound you want, without endangering your engine.My 2c worth

i rode mine for a little while when i was waiting for the stock exhaust to get here.. it was soo loud..just drill some holes in the mid pipe of your stock one or something..dont know how it would sound..but it should def. change the tone.
