no exhaust

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...

I understand you want instant gratification with your wants and can't wait until the money is available, but come on. If you want it to be louder for the time being take some of the packing out of the can to make it louder. DON'T take it all out because then your back to the scenario I mentioned before about having to rejet your carbs because of it leaning out.
OR
Focus on the important things like throttle control, braking, proper body positioning and cornering while you save up for the slip-on.
