Additional LOP Narrative HERE



Don't Be The Next Exhaust System Failure w/40, 50, 60 or 70 YO Pipes*


*Fortunately, this 1960 Debonair owner acted quickly and was able to get on the ground when his, now thin walled, exhaust stack blew out. Why risk it with ancient exhaust stacks. Exhaust system failures can KILL you with fire or CO!

Please avoid putting yourself in this situation-please chuck ancient exhaust pipes.

Below is what the owner purchased after his AOG situation. A great choice!
