Ignorance is bliss my friend.
So when a buddy installs a test pipe on his MS6 and a couple weeks later his exhaust starts smoking? On a meticulously maintained MS6 that was in perfect working order prior to that?
Fact is, it's an eventual happening. You don't need to be in denial with your turbo. Eventually with your mid pipe, you'll develop some form of smoking.
But, to each is own. If you want to deal with it, go ahead.
Smoking turbos = is a single factor analysis.
Not a single person with minor engine mods has a smoking turbo. Your theory of the engine running richer or adjusting it's fuel trims because of the intake, causing more oil to spew into the exhaust is hardly realistic and has no grounds of proof.
I've got the rest of the forum as proof. It's an obvious assumption given that almost EVERY time you install some form of exhaust modification to our cars, they will indeed smoke.
Don't believe me? Scroll through this thread:
