TT10730 MANIFOLD MGB P3 MILD STEEL Improving the gas flow through the engine is the key to gaining more power a simple first step 'Stage 1' is to upgrade the induction - please see our Performance Fuel Delivery & Induction and Performance Exhaust Systems. Fitting an extractor manifold with a performance exhaust allows the engine to breathe more easily. To gain the most benefit from our extractor manifolds and performance exhaust systems they should be used together. Extractor Manifolds work by allowing the gasses to flow through a smoother path. Using larger bore pipes also reduces back pressure in the manifold and cylinder head. Additional power can be gained by wrapping the manifold this reduces the temperature in the engine bay allowing cooler air into the carbs and keeping the exhaust gasses hot which means they have less density and flow more freely see our selection of Heat Insulation products. Our manifolds and systems are manufactured to the highest standards and are available in high quality mild steel or type 304 stainless steel. All pipes are mandrel bent to maintain tube shape and assembly is done on jigs to ensure accuracy and quality fit. This exclusive Moss Sports large bore extractor manifold uses 1 3/4" primary pipes with 1 7/8" exit pipe making it ideal for highly modified fast road and competition engines. This manifold is designed to be used with our Moss Sports Performance Exhaust Systems to maximise power potential. For other fittings please see Inlet & Exhaust Manifolds in the restoration section.
