One interesting thing we found about the Arrow headers. They produced no more HP & TQ in dyno testing than the stock head pipes, in fact they made less power. The problem is that there is no crossover pipe on the Arrows like the stock pipes use. What looks like a crossover is only two pieces of pipe welded to the outside of the Arrow header pipes with a slip joint in the middle. We had to drill out the inside of the Arrow crossover where it was welded to the header pipes to get a true crossover before the Arrow pipes made more HP & TQ than the stock head pipes.
