Well I'd post our numbers for you, but I don't have anything in front of me and most people wont' believe what you show unless it's done independantly. We spent 3 months on the dyno, and our exhaust either matches the stock curve, or is about 2 horse. I have some runs at 2 horse, and some runs were it's a half horse, to even, to 1 horse. We worked hard to just get back to stock in all honesty. I'll have them up on our web when I can get to it.
"Decibel numbers might be harder to get. I'll be dead honest with you guys. You are not going to get good acurate decibel numbers from anyone. And you are not going to be as quiet as stock. I do not care what anyone tells you, you CANNOT buy an aftermarket exhaust and expect it to be whisper quiet. Look, they are half the weight of stock, how can you expect them to be quiet. We try to get them as quiet as we can, but there is only so much you can do. Volume equals sound, less volume=more sound. You guys who buy or think about buying aftermarket exhaust all know what you are getting into. Yes there are some that are louder than stock, but still acceptable for the trail. Then there are some that are not. The guys who are trying to make an effort to make something that is quiet enough for the trails have a hard time keeping up with the ones who make loud #*$&@ because we spend 10 times more in development and build costs.
