check out hurricane headers by hardin marine sold by DIAMOND MARINE Bill is great to work with and has a great price on them. mine are 2 1/4''' inside id od is about same as cmi. 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. I will be testing by the end of june Ihope .had another surgery over the winter but am back at it with the boat. my motor is a 572 gellner 1100hp plus
. I hope it gets good mpg

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.
