No more stripped threads in the cast exhaust manifolds of our Opel 4-cyl. Cih and OHV engines. This set includes six studs and the six corresponding copper nuts to bolt the Y-pipe to the exhaust manifold, just as is done on modern vehicles. Yeah, not everything new is the devil’s work ;-)—sometimes it actually makes sense. Just like in this case.
Do you prefer the “old-school” approach for this connection?!? Of course, we also carry the original bolts in our lineup...
