    Has anyone here fitted a 3" exhaust system to the standard S3 catalytic converter is it a straight bolt on or will I need to get either a reducer or a piece of sleeving?
    (What is the standard system diameter?)

    thanks

    I thought I'd give this a bump as Id be interested to know the answer too.
