Thanks all. I ripped the exhaust system out yesterday (was duals)..tomorrow it goes to get media blasted!

If I remember right ever car gets one that is welded in Standard for single exhaust & then the second one bolts in for optional dual exhaust. Sometimes you'll have a similar plate in trunk especialy on E-Body's. LEON.
