| $150.00 per set For Pan’s and Shovel’s: holes are drilled and tapped. Our exhaust ports are welded onto your heads at the same angle as the original ones. Note: To make these work on your pipes, you will have to weld a plate on to your pipes to adapt to our 3-bolt flange, or use your Shovel pipes for now. We weld these exhaust ports on so your Shovel pipes will bolt up until you make the 3-hole plate. On Pan heads use 1966 to 69 Shovel exhaust pipes. Steel plate for pipe $10.00 more |  |
