sound more like valves to me... the exhaust should not cause smoke... it should just push it out the tail pipe... i would suggest valves and seals first...

smoke comes from bad valve guides and seals... if the valves are not bad then you can reuse them... the valve guides are 2.50 in general... but you should not have to pay ny more than that per guide...

you get white blue smoke because you need a new valve cover gasket??? that would only be under the hood not comming out the exhaust pipe... and if you have a bad valve cover gasket why not fix it??? or do you like the smoke look???

portion. what color is the smoke that comes out your exhaust? Most likely its not just because you have a custom exhaust.
