By altering the relationship between the primary length and collector diameter and length it is possible to increase or decrease the torque and horsepower output at any specific R.P.M. level. For a slick track the header primaries or collectors can be shortened to decrease the low end torque for better traction. Larger diameter collectors will also reduce low end torque. On a good track with lots of bite, extending the primaries or collectors will pick up bottom end power for a harder launch and awesome e.t.s. Smaller collector diameters will also increase low end torque. Hooker adjustable headers have taken more Pro Stock drivers to the championship than any other brand.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTuned Length Tubes For Max Exhaust Scavenging\/Velocity\u003c\/li\u003e\n\u003cli\u003eKeep Top End Horsepower\u003c\/li\u003e\n\u003cli\u003eLong Transition Collector For Decreased Back Pressure\u003c\/li\u003e\n\u003cli\u003eMost Durable Available\u003c\/li\u003e\n\u003cli\u003eAll Hardware Included\u003c\/li\u003e\n\u003cli\u003eLong Transition Collectors\u003c\/li\u003e\n\u003cli\u003eMandrel Bent Tubing For Smooth Exhaust Flow\u003c\/li\u003e\n\u003cli\u003eMonstrous Low-Mid Range Torque\u003c\/li\u003e\n\u003cli\u003eMachined Flange Provides Finest Fit\u003c\/li\u003e\n\u003cli\u003eProvides Finest Fit\u003c\/li\u003e\n\u003cli\u003eBest Industry Welds For Durable Design\u003c\/li\u003e\n\u003cli\u003eLong Tube Lengths\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSuper Competition Long Tube Header |  Black Finish |  Tube Size 2.25 in.
