    Exhaust flap

    Hey guys, nice quick easy question. With the engine off should the flap be open on an S3? I done the flap mod ages ago but reverting to standard for a service tomorrow. Can't remember if it needs to be open or closed though I think open.
    Map is being uninstalled as I write ......boo!

    Nobody? Anyone mind having a quick peak up the left hand pipe to see if it's open?

    Cheers guys. It is open. Drive to Audi was a bit sedate with the original map on. Might leave it on for a few days so when I put the stage 1 back on I'll be wowed again!

    Stick a Milltek on then put the map back on, I did this and it makes a big difference.
