Headers are one of the most common methods of improving an engine's performance. Stock exhaust manifolds create backpressure, restricting exhaust flow, because more than one cylinder shares the manifold. With headers, each cylinder has its own exhaust pipe. But all headers are not created equal. Many are made of plain steel that will rust and corrode. The head flanges may be thin, causing exhaust leaks. And there may be no thought to the shape or length of the header tubes other than fitting in the engine bay. Not so for aFe Twisted Steel Headers.
aFe optimizes the header tube lengths for maximum flow and velocity. Mitered collectors extend the tube length into the flange, which decreases turbulence and increases exhaust velocity. Pulse control technology improves flow, increases horsepower and torque, and improves throttle response.
Twisted steel headers are constructed from CNC mandrel-bent 14-16 gauge 409 stainless steel tubing for maximum performance, corrosion resistance, and strength, to eliminate cracking.495.00Brand: aFe Part Number: 48-46101 UPC: 802959480090

I installed this on my 2004 Ford F150 5.4L. I can definitely tell the gain in power. Haven't really payed attention to fuel gains yet. Very easy to install, directions were very nice. Overall, great so far!Was this review helpful for you? YesNo(5)APPEARANCEEASE OF INSTALLATIONPRICE/VALUEQUALITYExcellent Quality!| Posted by Paul G. | 2012 Ford F-150 (Anchorage, AK)
Easy to install; everything - bangers, bends fit perfectly. Beautiful quality, great sound... From a purring cat to a roaring tiger! I had more interest in increasing fuel efficiency - which may benefit, but not noticeably so at optimum fuel mileage speed. But at performance levels - wow! What a difference. Thanks! Great job at getting this product right the first out of the gate. Thanks, CARiD, for the great service, making this purchase happen so smoothly!Was this review helpful for you?

Installed the striker package onto my 2012 F-150 and can't believe the horsepower gain. Highly recommend this package to anyone who has the new twin turbo EcoBoost.Was this review helpful for you?

I've been running this exhaust for around two weeks. Sounds impressive. The install was easy. Just pulled the stock exhaust out, put the hangers on the aFe unit and put it in.Was this review helpful for you? YesNo
