when not at WOT, just accelerating normally does it sound like an exhaust leak ticking? I've had this system for about a year and its driving me insane. I've checked over the system many times for leaks, couldn't find one. I've take it to the shop about 5 times and they couldn't find anything. Is it just the way this exhaust sounds on the 3v motors? I can only really hear it when I'm in the car driving. I let my buddy drive it around a parking lot and it sounded fine from outside the car. I don't really know any better way to describe the sound, but does anyone know what I'm talking about?
