Gibson Cat-Back Exhaust System Dual Split Stainless Steel Regular Cab 4.2L/4.6L/5.4L F-150 2005-2008

With the torque boost this Stainless Steel Dual Split Cat-Back Exhaust System by Gibson brings, joyrides in 2005-2008 Regular Cab F-150s will change forever (69533)! With a decrease in backpressure as well, this system creates a new baseline for 4.2L, 4.6L, and 5.4L engines. Its 2-1/2” of mandrel-bent tubing forms the best pathing for exhaust flow possible, leading to a 15-20 horsepower average. A chambered and baffled muffler complements the enhancement, intensifying the exterior sound to a primal, throaty tone. Plus, it sticks to a low drone in the cab that makes this weld-free and easy bolt-on system a fine choice!
