Sonic EFRA #2678 .12 exhaust pipe

Sonic introduce the new EFRA #2678 exhaust pipe for .12 nitro on-road engines. Developed in cooperation with various top-drivers and successfully used by Patrick Schäfer at the Euros A and German championships, the latest Sonic pipe lowers the fuel-consumption for increased runtime while keeping a good balance of bottom end power and maximum RPM. The pipe is EFRA legal and available from now as pipe only or as a complete set including manifold, springs and silicon gasket.
