When it came time to replace that ugly stock H-pipe, we chose a tried-and-true MAC 211/42-inch off-road pipe. The H- was chosen over an X-pipe both for sound preference and because it would be easier to make it fit our wider 5.4 engine. The modifications required were similar to what we did to the stock H-pipe in Part 1. We won't detail them here as they are fairly specific to the fitment of this particular brand and style of pipe. It's nothing a competent shop can't handle fairly easily.
