I'm interested in these as well. What was the reason you didn't go with 'em?

first off it was the noise level...but I have D&D, so not much of a difference.

Others telling me that it similar to you just taking off your mufflers and run straight pipe, which in turn not good for your engine due to pressure and lost of power...I'm not exhaust guru or expert, but it make sense when think of it.

I'm still waiting for someone with experience with this that convince me to go with this stubby.

i wouldnt pay that much for $15 worth of exhaust piping you can get at the local car parts store...

might as well run open pipes

however running open pipes you can potentially burn your exhaust valves because the burning exhaust gases will escape faster than they finish burning

backpressure = torque and torque = feeling faster

but the point is to slow the exhaust gases down enough to do a full burn

its the motorcycle equivalent when highschool kids put a fart can on a honda.

is this a defense or an agreement?

[wannabfast]

im agreeing with the motion that its like a fart can for the hondas

not exactly... 

significantly changing the flow of air through the motor (cams, exhaust, intake, compression) will result in a change in fuel requirements.

too lean = higher combustion temps = burnt valves or pistons

too rich = deposits = hot spots = burnt valves or pistons

"Backpressure" is always bad for performance, because it limits the amount of air the engine can pump to something less than the cylinder's full capacity.  That said, reducing "backpressure" without appropriate changes to the rest of the equation will tend to lean out the fuel mixture.  This topic is fairly complex, discussions of "backpressure" oversimplify the equations.
