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...
