Injen 3" Stainless Steel Cat-Back Exhaust System with Titanium Tips for all 2013, 2014, 2015, 2016, 2017 and 2018 Focus STs.

When looking to upgrade your 2013-2018 Focus ST, most people start with a cat-back exhaust system. This all new 3" Stainless Steel Cat-Back Exhaust System from Injen provides maximum horsepower and torque gains across the entire power band. Injen's cat-back exhaust system is a direct replacement for the restrictive factory exhaust on your 2013-2018 Focus ST.

This brand new Cat-Back Exhaust System is manufactured from 100 percent 304 stainless steel for a long lasting, rust free look. Every exhaust system Injen manufactures features mandrel-bent stainless steel tubing which is TIG welded for strength and durability. If you are looking for a nice, deep aggressive sound, this Injen 3" Stainless Steel Cat-Back Exhaust System is a great way to stand out in a crowd. Injen designed this exhaust system with dual titanium tips to match the contour of the Focus ST's rear exhaust cut out in the bumper.

Please Note: Ford designed the 2015 Focus ST with four exhaust hangers but only added three on the factory exhaust system. All aftermarket exhaust systems are built to use that fourth exhaust hanger. CJ Pony Parts recommends the purchase of COBB’s Polyurethane Exhaust Hanger Kit (591001).

Injen's 3" Stainless Steel Cat-Back Exhaust System was custom dyno tuned for the 2013-2018 Focus ST with significant gains in horsepower and torque. You can expect to see an additional 17 horsepower with 15 ft-lbs of torque out of your 2.0L Focus ST EcoBoost engine. All the O2 bungs in the exhaust are in the same locations as original exhaust system.

Since its launch in 2013, the aftermarket parts selection for the Ford Focus ST hatchback has grown considerably, and CJ Pony Parts has added these parts to their lineup, giving you tons of options to upgrade, style and increase the performance.
