The CMI 496 Sport Tube Performance Package delivers improved performance across the entire operating range of any 496 engine package. When applied to a stock 496 engine, this package will help to increase horsepower, boost mid-range torque, improve fuel economy across the power curve and enhance the engine's overall running quality. The package comes complete with all required mounting hardware plus CMI's exclusive 496 Relocation Kit, which includes all brackets, hoses and hardware needed to make relocation of select engine components easier.
Stock Manifolds Are Restrictive
Stock exhaust manifolds reduce exhaust flow, reducing power and economy. Headers promote better scavenging, improving exhaust flow, increasing efficiency and power output. Our performance kits increase your engine's ability to breathe and will show maximum gains when coupled with long tube headers.
Integrated Collector Merge Spike
Too much back-pressure can make it difficult for your engine to expel exhaust gas, limiting engine power. Stainless Works long tube headers feature integrated merge spikes which reduce back-pressure and turbulence within the collector. Inspired by race technology and performance dyno testing, the Stainless Works merge spike was developed to direct airflow towards the center of the collector, which promotes scavenging and further improves power gains from these long tube headers.
"Header-Proof" Ceramic Spark PlugsCeramic Spark Plug Wires - $340
8.1L engines with short and long tube headers routinely melt stock plug wires and even performance spark plug boots. Ceramic spark plug wires eliminate burnt spark plug boots in boats, trucks, hot rods and RVs. If you've had this problem before or don't want to worry about it in the future, check out our 45 degree ceramic plug boots which are rated to withstand extreme temperatures up to 2000°F!Ceramic Spark Plug Wires
