I installed the heavy duty clutch plates and heavy duty springs. I still have clutch shutter. Is there anything I can do to stop the clutch shutter:dontknow:? I also am wondering if anybody knows were or how I can get a Y pipe for my next exhaust idea? I am cutting down a set of aftermarket exhaust pipes and I need a Y pipe so I can install a 5in supertrapp exhaust muffler.
