Bolt-On X-pipe kits for ’86 to ’07 Pony cars smooth out sound and turn up performance.
Whittier, Calif. (July, 2012) –A true dual exhaust was the hot ticket until enthusiasts started adding H-pipes to change the sound and performance of traditional two-pipe systems. Unfortunately, turbulence in the merge area led tuners questioning how they could eliminate firing order pressure differences between the right and left banks of the exhaust manifolds, and free up more horsepower. The eventual answer to the question was the X-pipe exhaust equalizer system. The X-junction smoothly blends exhaust pulses from the left and right side engine banks to produce a smooth exhaust note, and increase volumetric efficiency of the entire system, resulting in increased power. Dyno testing of Hedman’s system for a 1985 Mustang GT, by a leading Mustang publication, demonstrated an increase of 35.3 Horses and 28.5ft lbs. over the stock, baseline dyno pulls.
