We have spent the last year on research and development on our popular Copperhead 65 (classic) and came up with a slightly larger and reconfigured Copperhead 80 pipe. These work great on OG big bore china doll engines, Falcon 911s and other china doll exhaust port varieties like our popular Venom 80. This pipe rips hard and it’s priced right so everyone can try one. We upgraded to heavy duty 19g steel, offer a slip fit header and as with all of our pipes, a branded silencer that keeps the neighbors happy.
