Flaps have already been done in a ton of OEM stuff. Honda and Ford for sure. It just puts a restriction in the exhaust though which isn't good either way. And the guy who was saying true duals make so much power - did you see his post about his dyno run? He made a wopping 13xHP!!! Man, I gotta get some duals!!! He's got all these mods and he's getting stock level power. What a bonehead! :rolleyes:
