Has anyone ever done this? I've been hearing of several people doing this, but I have not been able to speak to someone about the cost vs. outcome or difference in performance. I have an '03 Merc 40 (2-stroke, 3-cylinder) that I was considering doing this to. I'd mainly like to know if you also have to change the exhaust tuner. Any info would be greatly appreciated. I'm new to posting on hear, but not new to reading. Lot's of good stuff and apparently good people as well...Thanks ;-)
