Exhaust for 67 Cutlass 4Dr Holiday

[olds01]

Does anyone have an estimate price on single or dual exhaust for my 67 Cutlass 4Dr Holiday 330 V8 Jetfire

If you car is single exhaust now and you ask a shop to do dual exhaust they will say they cannot do TRUE dual exhaust without changing the exhaust manifolds. They are right, you need to find some dual exhaust manifolds or have your singles modified to remove the crossover ports and block them off. Then the shop can run true dual exhaust from the engine all the way back. I did this and the price of the exhaust pipes/hangers/mufflers cost me $250. In Boston it might be $400 and in Nebraska it might be only $100, labor prices make a big difference.
