Gibson Cat-Back Exhaust System Single Stainless Steel Extended/Crew Cab 4.6L/5.4L F-150 2004-2008

For an exhaust that goes beyond a domineering sound, opt for Gibson’s Stainless Steel Single Cat-Back Exhaust System in your 2004-2008 4.6L or 5.4L F-150 (619618)! From 10-15 average horsepower gains to 15-20 lb/ft of added torque, this system gives Extended and Crew Cabs serious power. It stems from 3” stainless steel, mandrel-bent tubing that lends itself to boosted acceleration and hill climbing capabilities. With the baffled and chambered muffler’s support, it builds better towing and passing power. But don’t worry about a deafening cab because while the exterior roars, the interior drones. With hardware and OEM-style hangers supplied, it easily bolts on without welding.
