Does anyone on here have a Gibson Exhaust system? I have read tons of people with Magnaflow's and Flowmasters but no Gibsons. I am going to be buying an exhaust system for my 05 FX4 next week and I am leaning toward the Gibson extream dual system. Does anyone have it on their truck? I had a Magnaflow system on my Jeep before and they sound geat but i wanted to try something different this time. I was also looking at the Flowmaster Force II Dual Rear/Dual Side Exit System or Flowmaster 40 series with custom tubing. I just want a great sounding exhaust that will not make you deaf on the highway. I would really like to know if anyone has any experiance with Gibson because it is hardly ever mentioned.
