Ok, first of all, you don't "need" backpressure to make it run right. The amount of exhaust restriction can change the power characteristics, but you don't NEED it. Keep in mind that a larger diameter exhaust pipe or header isn't always advantageous because it can reduce the exhaust pulse velocity, which also helps scavenge the combustion chamber.
Yes, your carbs will need to be rejetted and in fact, the throttle response may never be as good as orginal, if orginal was actually good,
You won't crack pistons because of cold air being sucked into the cylinder. There's enough high temperature metal around there that the outside air is going to be warmed up and if you think about it, what are you sucking into the cylinder in extremely cold weather? Cold air.
And don't even get me started on the "It'll burn valves" myth that so many people seem to believe. That ain't gonna happen either.
Just remember that increased noise doesn't always equate to increased power. Properly designed, an exhaust system can be quiet, minimize restriction and maximize power output.
If it's too quiet and all you are looking for is sounds and don't compare about performance then buy a cheap slip on. If you're going to run it open exhaust invest in ear plugs...
but like ya said doesnt apply to our bikes unless sum1 runs w/o the headers or cuts them too short.other than that I agree, get a slipon, open pipes sound like shyt except og top fuel cars and Harleys

I'll chime in. Back in the day I had a minty all stock F3 (swb) with less than 4k mile. At the 8th mile was runnin consistent low 7.3x. removed the pipe for ****s n giggles and ran high 7.2x... take it fwiw.
If you wanna be a cheapo, just chop your can. it looks cool and sounds way better. just my .02
