i have mine with 4" piping with an inline bullet muffler dumped right before the axle, so almost all the way back.
also making a reducer to 3" around the axle to a catback for quiet street driving.

mine is a 4" DP strait out of the ST80 turbo all the way back. i have no AC obviously and the DP goes through the passanger side of the motor where the compressor once resided. then 4" all the way on back to a 4" diesel muffler actually lol and it turns down before the axle.
