Right then, ive seen a few threads about exhaust diameter in the past now what about length?

Does the length need to 'tuned' at all or will putting a significantly shorter item on be a problem?

Say it was half the length of standard, exiting elsewhere, any issues? On a well tuned LET BTW.

Majority vote is for least restriction possible. Seen a few that are simple short dump pipes (on rear engined cars).
And others like the Dahlback (?) Golf which exits before the rear wheel.

Willing to be proven wrong, but I don't buy that one. The seal is in the housing, which is before the exit of the turbo. Can't see how back pressure (unless a LOT) would affect the seals, unless they were knackered anyway.
