Probably the best setup on the marker right now for the longtube headers.
Dynatech Header System for 2004 & up F-150 with 5.4 3V
122-622100s
Dynatech Longtube Header System including complete High-Flow Catalytic Converters & Y-pipe Assembly.
These beautiful Longtube headers are the only TRUE BOLT-ON setup available for your 2004 & up F-150 5.4 3V!!
This is a true bolt-on setup that will mate right up to any existing cat-back exhaust system, from the stock factory setup to Magnaflow, etc., cat-back exhaust systems.
Power gains will vary based upon boost level, but typically run in the area of 30 RWHP in supercharged applications running lower boost levels, a bit less in normally aspirated applications.
Far more important is what happens to the torque curve - it is extended everywhere, instead of hitting it's peak and falling off quickly, it is extended out significantly, and this aids mid-range power for anything from towing to performance applications, or even normal everyday driving situations.
No "shorty" type of header system can begin to compare to the results, effects and sound of this system, yet there is no "droning" inside the cabin. This extension of the torque curve is critically important in aiding torque & acceleration when driving hard, but also even fuel economy during normal cruising. For example, on our own 2004 5.4 3V F-150, we have averaged a gain in MPG of right at 1.0 MPG overall with or driving conditions, a result we were amazed at in our 6000 lb supercharged 5.4 3V truck!
These headers feature laser-cut flanges & mandrel bends, and are made of T304 Stainless Steel (including hardware!), use 1 5/8" tubes, Magnaflow high-flow cats, and already have both the upstream AND downstream O2 sensor bungs welded in! So all you need to do is to simply screw in all of your factory O2 sensors once you install this system, and it is very easy to install. Your OBD-II system will work as designed from the factory, no more having to run illegally by having your tuner turn off the rear O2 sensors, etc.
No ceramic coating is required due to the heat-retention characteristics of these stainless steel headers and everything fitting to the factory heat shields, etc.
No tuning changes are required from using these longtube headers in 99% of the trucks we have installed them on, unlike some other longtubes.
There is no better quality header than Dynatech - forget trying to go the cheap route with Pacesetter, etc., it's just not worth it when you can get aircraft-grade T304 S/S quality like this that will last a lifetime without cracking, etc. It's just not worth saving a few dollars at time of purchase - if you are going to install headers, do it right - do it ONCE - with Dynatech, just like we do in our own vehicles here at Troyer Performance.
Installation time generally runs about 6 hours, and some of our customers have reported getting them done in as little as 4 hours - no more 8-12 hour jobs fighting the engine height, etc., as with so many other headers for these trucks!
These Dynatech Longtube headers come with ALL hardware needed and it's of the best quality, too. You will also receive the finest quality multi-layer exhaust gaskets money can buy, the highest quality O2 sensor harness extensions and excellent step-by step instructions with plenty of photographs. You will never find an easier to install set of headers!
