    Recommended Upgrade. To realize the full power potential that this Long Tube Header and Off-Road Shorty X-Pipe combo kit has to offer, AmericanMuscle highly recommends a Bama custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

      Gt500 headers

      Best upgrade ever if your one of those people who want to sound like your gonna eat your neighbors children coming down the road these are for you. Fitment is excellent but will say it is not an at home garage install as the 5.4l doesn't leave you much room. These with a Roush muffler sound how it should come factory.

      Great product

      These are great, the sound you get is awesome, loud when it needs to be and quiet when you have to be, like going into your neighborhood at 3 am on a weekday quiet. The power gain is also present. With a lift its simple to get these into the car and bolt them up!
