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.\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul class=\"productpage_list\"\u003e\n\u003cli\u003eMost Durable Available\u003c\/li\u003e\n\u003cli\u003eProvides Finest Fit\u003c\/li\u003e\n\u003cli\u003eKeep Top End Horsepower\u003c\/li\u003e\n\u003cli\u003eMonstrous Low-Mid Range Torque\u003c\/li\u003e\n\u003cli\u003eLong Transition Collectors\u003c\/li\u003e\n\u003cli\u003eLong Tube Lengths\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Hooker Headers","offers":[{"title":"Default Title","offer_id":48111748612405,"sku":"CLR-HOK-5320-1HKR","price":1099.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0859\/6209\/6949\/products\/F118122441__33551.1649376541.1280.1280.jpg?v=1707558311","url":"https:\/\/fcrcmachine.com\/products\/hooker-headers-super-comp-headers-1962-1974-dodge-chrysler-plymouth-bb-5320-1hkr","provider":"FCRC Machine","version":"1.0","type":"link"}
