Hooker 13/4-inch Headers: 261 hp at 5,100 rpm, 321 lb-ft at 3,400 rpm
We replaced the shorty headers with Hooker 13/4-inch Super Comps. Long-tube headers provide a tuning effect based on the primary length. Just like runner length in the intake manifold, the headers help scavenge the exhaust and therefore help draw in the induction charge. These pipes increased the power output throughout the rev range. The peak numbers jumped from 252 hp and 306 lb-ft to 262 hp and 321 lb-ft. The Hooker headers improved torque production by as much as 25 lb-ft at 3,000 rpm.
