Exhaust Idea

XR-1`s are no different than a regular glasspack so save your money and go cheap with the glass packs. also the shortie headers really don`t offer any advantage in power over the stock headers. LT`s will add up to 15 hp and give a deeper tone.

This is when I differ with your opinion. My brother is currently using them on his '97 F-150 4.6L and it sounds distinctly different than the other 4.6L F-150s that I have heard with other glasspacks. These borla's also are a triple-chamber design that split the air into 3 separate flows that are separated the disance of the muffler and are left in these 3 flows until the muffler ends, which can easily change the audible characteristics of the exhaust. And my brother's sound is so distinct, that no one confuses his approach with any other vehicle.
