Okay I was driving today and all of a sudden my motor starts to sound like a boat. Somewhere the exhaust is leaking. I am guessing it is the headers. I know I am missing a bolts, the motor was to hot to touch so I let it cool down. I did see at least one missing. I was size are the haeder bolts. And what length are they?
