I ordered a Force II system to ensure a cat back compatible system. The system consisted of a resonator pipe, muffler, and tail pipe, all 3 in. diameter. Assembly was very straight forward with the parts all fitting nicely together. As a senior citizen working alone on the ground with the truck backed up on auto ramps, it probably took me about 4 hours. Most people could probably do it in two hours or less. The system is quieter than I expected but should be pretty efficient.
