exhaust leak
#6
where the rear manifold meats the downpipe theres a donut gasket in between there. Any parts store should know what your talking about. Its an easy fix, just remove the bolt/springs from both sides, take the old material off (if there is any, for some reason there was none on mine) put the new gasket on, tighten up the bolts and springs. Its always good to replace the spring and bolts, usually $20 for a new spring and bolt kit, and the donut is about $5-7
