This is the RB Concepts CX .21 9-Port Competition On Road Engine with an included 2092 Tuned Pipe. The CX (Circuit Xtrem) is the little brother to the CXR with similar performance but at a friendlier price. It features a 14.5mm turbo crankshaft, turbo plug use, turbo combustion chamber, 14.5mm main bearing, lightweight aluminum carburetor, CNC machined piston, competition conrod, lightweight crankcase and a lightweight cooling head that sits lower on the engine for a lower center of gravity. The CX is certainly a very good choice for your 1/8 scale on road car.

The RB Research and Development department, together with RB team drivers, have developed a redesigned EFRA legal tuned pipe exhaust system, the RB 2092. Designed to provide increased torque, the RB 2092 tuned pipe comes polished with shifted pressurization and includes a manifold, seals and hardware.
