Dry tail pipes
 

Are there any shops out there who can modify my three piece tail pipes to a singe piece dry or do I have to have a new set made?

These actually have a silicone coupler on the inside that you can see in the pictures, then have a tips that slide in from the back of the transom. If the coupler loosens the tip can slide out and exhause / water dumps into the bilge. Had it happen over the weekend and it made a mess.

you will need to make new ones, and install dumps for the water exiting the new tails. will be quite a bit louder.

The louder the better.
