The Twister, Part II
|
Smaller headers like the 1-5/8-inch Hedman's we tried often fit better in the chassis and tend to pump up the midrange and low-speed torque. Adding larger 1-3/4-inch headers tends to increase peak power while costing a little torque below 4,000 rpm. Our testing used Hedman headers for both 1-5/8- and 1-3/4-inch primary pipe sizes.
