    Unplugging S3 Exhaust valves

    Thanks for all the responses. After driving it for a week or so with them unplugged, I can 100% tell the difference now! Time for a res delete aswell I think, might get in touch with BCS for the anti drone pipe.

    Unplugging S3 Exhaust valves

    I just followed this video and unplugged the valves on my S3 8V FL. I've been out for a blast in it and really cant tell any difference? Should there be any noticeable difference and is there any way to tell if the valves are in fact open? Cheers
