Message	wouldn't you think? I would think the seals on new turbos would not need backpressure. I don't KNOW this, but it makes sense to me. Are the seals on sport 500s different from the ones on stock turbos? Because I know plenty of people with stock turbos and cat-free exhausts whit no smoking issues.
