I put the new engines in my boat and I am hookong up the exhaust.I have to send my tubes back to Stellings to get lenghtend.I have shotgun silencers on them.My question is how far do you think the exhaust should stick out the transom.The boat is a 32 Maelstrom cat and has a 10'beam.Please chime in as I have to make a decision tommorrow.Thanks Fishead

3"-6" should be plenty

If you are still going to use the Shotguns, I would think that you would what them to attach to the pipes on the outside of the transom. This may be your deciding factor on length.
