give it a couple days and see what happens. if it don't stop by the second day, take it to the dealer. if your exhaust smells funny, you could be running too rich or too lean, or you could have a cat starting to go bad. as far as the clear smoke goes, condensation builds up in the exhaust. now that you have more exhaust, you have more condensation. that's normal, mine does it too. but keep in mind that when you install a new part that will actually get hot like the exhaust, that you are handleing it with dirty hands. weather it be from grease from the car or oil from your hands, when it burns off it will smell funny. if you would like it louder, you can always just take the mufflers off and replace them with regular pipe. i did that to mine aswell. that made it a bit louder, but not quite enough for me so i also added exhaust dumps right behind my x-pipe. now it's loud. i dig it, neighbors hate it. lol well good luck! | 
Went Dual, More Smoke?
