I’ve done a few searches and can’t find what I’m looking for. I want to modify the muffler on my 361 to get more power, and to keep things cooler. I love what a duel port did for my 660, but having never modified a muffler I’d like to see how some have successfully done theirs. I’m comfortable with the carb retune, it’s just the what and where to modify that I’d like some guidance on.
