Customer Real-World Review:

 "We sea trialed the 40ft Garwood after installing your 5”x16” muffler inserts. Upon startup was immediately noticeable the change. Left the dock and we were able to have a conversation at the helm from idle thru W.O.T.  Being as I was the mechanic that sold these mufflers to the Captain with caution that I cannot guarantee the results, I was very impressed and so was the Captain. Owner has yet to experience and I’m sure he will feel the same. 

Thank you,

John
