Rated as the best exhaust system for effectiveness, quality, and reliability, in “How to Power Tune MGB 4-Cylinder Engines”, this system typically boosts mid-range power at the wheels by 5 b.h.p. Pipes are slightly larger in diameter than stock, and the single muffler is larger than standard. Silencing ability is excellent, producing a deep, powerful, but not unpleasant exhaust note. Available separately, the Peco Exhaust Header mates up perfectly to this larger bore system.
