Exhaust
Adding a downpipe,a midpipe in place of cat and a greddy cat back to a stock engine have any detrimental effects ? or do i need to add other items to keep from blowing engine ?

CB and DP may add up to boost spike. The MP will cause boost creep. Both can blow your engine if you don't add fuel or keep your boost under control. Do a search, there's lots of info about these mods.

If he gets boost creep from the midpipe, I don't think a BC will help. Either port the waste-gate or leave the cat in place.

Yes, that should be fine.
