sounds like my car!! its because its got and open dump. I have a 3-inch downpipe with a Y in it. one goes stock and the other has an electronic butterfly valve. but let me tell you, when you step on it, it is so loud you can barely think-you literally have to scream to talk to the passenger in your car. but you cant beat the turbo whistle when your pulling into the parking lot!!!!! =D
