Description: For cars and trucks. The quirky exhaust-flow characteristics that result from a V8's firing order can both hold back power development and reduce fuel economy. However, the tangentially siamesed design of the crossover junction at the center of Hedman's X-TREME X-pipes takes care of those problems by smoothing out pressure differences. That improves the volumetric efficiency of the system and delivers more power across the entire rpm range. These systems are made from aluminized tubing, are available in different diameters, and will fit many cars and trucks. (minimize)
