By the way, I finally chased down my o2 sensor engine light codes to leaky HFC gaskets. I've installed Zspeed gaskets and Silicon sealer, and my codes are gone and my exhaust sounds right again. It was tight doing it without a lift, but saved me a couple hundred bucks labor. (the bolts were a bitch though and required an impact gun to bust loose)
