i have a 2009 yamaha grizzly 700. i just replaced the exhuast with a big gun exhaust. it really boosted the performance, and sounds good, but its way tooo loud!! people can hear me coming from miles away. i cant believe that the reviews i read before buying it didnt talk about how loud it is. it hurts my ears and gives me a head ache, and completly takes the fun out of riding thru the woods on a four wheeler. i wanted performance but this is rediculous. sounds like a raptor running open exhaust. i also bought the quiet insert and installed in it. that was a waste of 25 dollars. it didnt make a difference at all. i want performance exhaust but im not willing to sacrafice a head ache from it being so loud for the performance. does anyone have any ideas on how to make it more quiet? or a performance exhaust that isnt so loud? thanks, matt
