This V-8 manifold will dramatically improve both power and torque - - and at an affordable price. Easy to install by simply unbolting the old manifold and bolting on the new. The PowerFlow manifold is unique in design. Over two years of testing and development went into producing this exhaust system. We have documented increases of 40 to 50 foot pounds of torque and horsepower in stock engines and 80 to 90 foot pounds of torque and horsepower in high performance engines up to 575 cubic inches. PowerFlow manifolds are manufactured using finest materials and most advanced techniques available. Our high quality aluminum manifold castings feature water jackets that surround each exhaust passage, including the port, to eliminate the possibility of burn out. The inside of the water jackets are coated, using a special hard anodized impregnating process to prevent corrosion and leakage. Our coating will not flake off and clog water fittings like conventional powder coat paint. The outside manifold surfaces are coated with the highest quality epoxy powder coating available, creating a part that is not only highly corrosion resistant but good looking as well.

PowerFlow stainless steel, water jacketed exhaust pipes are high polished, free flowing and water jacketed to eliminate hot spots toward the top of the pipe. Water flows directly through the flange from the manifold. A built in fitting accepts a stock MerCruiser thermostat connection. PowerFlow exhaust pipes are available in several different stainless, water jacketed, riser pipe configurations. All plumbing, fittings and accessories remain in the original location.

We shed unwanted pounds. Our aluminum manifolds weighs 80 pounds less than the stock version. Ideal for EFI equipped engines, as they require no calibration or program changes. Twin installations will work down to a 33" center. IMCO PowerFlow exhaust systems are available for Chevrolet, V-8ís in both big block and small block. Ford 460 adapter available. Look for big increases in horsepower and torque with a PowerFlow exhaust system.
