I went with 5'' tails dry.but have a stud to remove for a little water to cool mufflers if needed. there 316ss made same as tails, where cmi uses 304 I think for tails.

More steam then usual. Also if you pull the header off, there might be a collection of water. It's worth pulling them off in the middle and end of the season to pressure test them....could save you a lot of money in the long run.
