Bolt this BMP high flow manifold on your F7/M7 or Crossfire 7 for an instant power gain using the stock or aftermarket single pipe. Noticeable gains in low to midrange acceleration and punch. Up to a four horsepower gain on some models with no other changes needed. Carb models have shown even a larger gain than EFI models. Works on all 2003-06 F7, F8, and F9 motors. 2003-04 models will come with a new updated pipe mount. A must have for big bore or stock motors!
