I'm going to buy a 03 FX4 Screw in the next couple days. (Hopefully today ). It has the 5.4 with the automatic. Tuner to come after mods but wanting some info on mods.
I'm doing Gotts mod. Electric fans. Exhaust with rear cat delete and true duels. The truck has a little over 1000,000 miles and will see a lot of highway miles as I plan on doing some traveling. Questions 1) What size exhaust ? 2 or 3 inch 2) H pipe worth it ? 3)What mufflers ? I want it to be heard but not obnoxious. Deep sound. 4) What electric fans work the best ? 5) Any other ideals greatly appreciated ![]() Trying to get the bang for my buck NEED gas mileage and HAVE to have POWER ![]() Thanks for input |

I hope you enjoy the truck, the only other thought is if you want gas mileage... get a motorcycle! ![]() |

Ok a little update : exhaust is 2" with magnaflow muffler with the two in two out. Sounds great ! Have supplies to do Gotts mod just havens had time. Looking into flexalite. Fans now. Gas mileage has been average 13 mpg hoping to get that up when all is done. Looking at the Griffin tuner.
Thanks for the advice and anymore is always welcome. |
