One of the biggest restrictions of power on a performance turbocharged car is corking up the exhaust gasses from the turbo. Factory Down pipes sometimes have smaller diameters and have very restrictive catalytic converters. Freeing up this exhaust flow is the easiest way to increase horsepower and torque through the RPM band. Agency Power's 3 inch stainless steel down pipe is a direct replacement for the factory pipe. Designed in a modular way so it can be used with the factory catback exhaust or an aftermarket catback, the down pipe is built from T304 stainless steel and then TIG welded. It utilizes the factory mounting points with the attached hangers.
Typically a down pipe will also give you a little boost creep allowing for your turbocharger to truly maximize its programmed boost potential. As tested on a Mustang Dyno, the down pipe carried horsepower and torque gains from 3700rpms to redline. At 5500rpm, the down pipe gave the ST about a 20hp gain with an additional 15ft/ lbs of torque!
The down pipe is built to fit the 2013-2014 Ford Focus ST.
