" Installed easily on my 2003 F250 Super Duty 5.4. No major problems getting them to fit, etc. Really opened up the horsepower in the truck too-I've noticed a significant difference in the low end take off power. Haven't seen gas mileage difference but probably because I'm having so much fun I can't keep my foot out of it yet. "

" The Gibson Headers are awesome. They look sharp on my Bronco and there is an increase in "low end" power. The headers also reinforce the sound of my Gibson Swept Side Exhaust, creating a nice low purr. Together they are spectacular. The combination has increased compression and the engine is actually running cooler. "
