50 trim in - lot's of smoke from exhaust

[BKs50trimGST]

ok, i bought my oil drain pipe from buschur racing, the one where u have to modify your stock drain pipe and then use a rubber hose and the modified end for the 50 trim. When i put my first 50 trim in and it was blown so alot of oil got into the exhaust, but the thing is i drove an hour on highway, i was going fast the whole way home to, i'm not saying i was boosting the whole way home either, but everytime i shifted smoke came out, and i know for a fact it can't be the turbo. i don't see any leaks, do u think it's just the exhaust burning off the oil in it, i don't think it's possible because i drove the car alot last night. also, i have a brand new SS exhaust to, so i don't know if it's just the paint or whatever inside the exhaust getting burned out. i smelled oil, that's why i'm scared it might be something bad happening. i just don't know.
