Coming from Reds Racing is the new EFRA 2143 off-road exhaust pipe. Designed to improve fuel economy and torque of Reds Racing’s own engines, the pipe, in combination with the S manifold, will increase the runtime by about 30 to 40 seconds, depending on the track and surface grip. This means up to nine minutes of runtime can be achieved with the Reds Racing R7 Evoke and the Quattro 4-shoe clutch. Additionally the torque will be increased by about 5 percent, and a more precise throttle response in the low to mid RPM range can be felt. The pipe is available separately or including the S manifold.
