Yeah im running shorties at the moment and im just not happy with the sound although a great product
If you bought the truck with the shorties on already, you are not going to loose anything by changing them to long tubes. Just get as much info on them as far as a swap before taking on a challenge like that 04 to 08 sounds like it can be a real pain the the backside to do on the 5.4, even with shorties
Just some information for those wondering...it has been proven and I have seen first hand that shorties do not make any extra power on modular motors because of how efficient the factory manifolds are. Shorties on a modular motor are strictly used for sound purposes only. The only way you will see a power or gas mileage gain is by switching to longtubes. Check companies like pacesetter or flowtech for headers for your application because they make a variety of low budget longtubes for many years and engine combo's of Ford trucks.

guys, im running a 94 5.0efi. not a modular motor.
Crawford- because of whats called the scavenging effect, or how the engine pulls exhaust away... kinda has to do with backpressure.
Speed- 30 is a bit overrated, maybe at the crank youll get that much, but at the wheels will be more like 10- 15.... depending on supporting mods as well.. not trying to belittle you, it s just exhaust manufacturers like to advertise stuff like that for profit.. i find it a bit misleading..
Long tube headers or shorties?
