    And the S3 exhaust has those vacum controled valves in the exhaust to "apparantly" make it shound better!

    I guess the valve would stay shut unless you have the vacum pipe! Unless the Derv's have this as well!

    They are completely different anyway, unless your Tdi is a quattro? Due to being quattro the rear floor and exhaust is a bit different on the S3
