FSWERKS Performance Headers
Our FSWERKS 4-1 Race Header is designed for track use and plays a very important role in maximizing exhaust flow for all out performance for your Zetec Focus. Construction consists of 16-gauge heavy-duty steel tubing and laser cut flanges measuring a full 3/8" thick. We use 1 5/8" diameter mandrel bent runners which merge into our 2 1/2" ID collector for maximum flow. Since the Race Header is for track use, it does eliminate the factory emissions equipment, but we do provide fittings for the EGR valve as well as the oxygen sensors. The FSWERKS Race Header will give lightly modified cars a 6-7 horsepower gain and an increase of 4-5 lbs. of torque* measured AT 
THE WHEELS. Highly modified cars, such as our FSWERKS project Focus have yielded gains as much as a 25 horsepower** gain and an increase of 13 lbs. of torque**, measured AT THE WHEELS. Finished in a polished ceramic coating that can withstand constant temperatures of 1200° Fahrenheit.
Dyno Sheet 1 shows our base Focus run vs. our modified Focus run. Mod parts include FS Exhaust, FS Cool-Flo, FS Wires, chip, Kent adjustable gears and cams set at stock cam timing, and FS cylinder head. No aftermarket header was used, only factory exhaust manifold and catalytic on Dyno Sheet 1. The Dyno Sheet 2 shows what kind of gains you can get with a modified car "with" the race header, FS Exhaust, FS Cool-Flo, FS Wires, chip, Kent adjustable gears as well as cam timing adjusted for max performance, and FS cylinder head.

* Stock cam timing was used in testing. Greater horsepower and torque figures can easily be achieved when the intake and exhaust cam timing is adjusted for performance.
** Intake and exhaust cam timing was adjusted for maximum performance.
FSWERKS Extension Pipe with Flex Joint
Designed to be used with our Race Header to help maximize exhaust flow. Construction consists of mandrel bent 14-gauge aluminized steel tubing, 3/8" thick flanges, and a 2 1/4" diameter stainless steel flex joint. We replace the 2" diameter OEM unit with our 2 1/4" diameter mandrel bent Extension Pipe with Flex Joint, which connects to the Race Header collector flange and then also connects to the flange of our FSWERKS exhaust system.
