    Yes, but you might need to modify the link pipes between the downpipe and the rest of the system.

    so its mainly just the join to the turbo thats the same?

    i know im going to sound stupid here, but is it possible to make an s4 exhaust fit an a6, just by extending it, or is it completly different, i only ask, as for a decent one for my car, its nearly £1k, but for an s6, its half that?

    S4 floorpan is fairly different.

    Should be able to mate an S6 system up to the S4 downpipes/cats without too much work though.

    yep cant see no reason why not.

    RS6 system would probably fit too, but you'd likely need to modify the rear bumper.

    And for £99 your not doing much better!

    I guess it depends how loud you want it.

    Theres a big difference between a tasteful burble, and saxo-chav levels of ear bleeding exhaust noise.
