COBB 3" Stainless Steel Turbo-Back Exhaust System with Catalytic Converter and Dual 4" Tips for 2013, 2014, 2015, 2016 and 2017 Focus STs.
COBB's 3" Stainless Steel Catted Dual Tip Turbo-Back Exhaust System is a direct replacement system for your 2013-2017 Focus ST. The exhaust 591301 features full 304 stainless steel construction, a high flow catalytic converter, custom inline mufflers and dual 4" double wall stainless steel tips. Installation of this system results in a drone-free and unique exhaust note.
This 591301 COBB 3" Stainless Steel Turbo-Back Exhaust System with Catalytic Converter and Dual 4" Tips includes a COBB 3" downpipe and 3" cat-back pipe put together in a kit for a complete bolt-on exhaust system. Full stainless steel construction means the COBB turbo-back holds up extremely well under the stress and assault of the elements. Beautiful TIG welds seal all lines perfectly, resulting in zero exhaust leaks. CNC mandrel bent tubing creates the perfect fit every time for a no-hassle installation.
The downpipe is 3" in diameter with a 4" flex section. The COBB downpipe features a 200 cell count Magnaflow catalytic converter. This high flowing cat decreases restriction for better exhaust flow. The COBB downpipe bolts up to your factory turbo with a V-band flange. Although a 2-1/2" gasket is included to bolt-up to a factory cat-back, the 3" gasket is used to connect to the COBB cat-back for a perfect seal and unrestricted flow.
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).
COBB custom inline mufflers produce a sound unique to the COBB exhaust system. Minimal restrictions increase exhaust velocity for the best bump in horsepower available. Dual 4" slash cut, double wall tips feature the COBB logo and look fantastic exiting the rear of your 2013-2016 Focus ST.
*Includes all necessary hardware and installation instructions.
Pair this COBB 3" Stainless Steel Turbo-Back Exhaust System with Catalytic Converter and Dual 4" Tips with a COBB Accessport V3 Tuner for a fantastic bump in horsepower on your 2013, 2014, 2015, 2016 or 2017 Focus ST. COBB offers ready-to-run maps to maximize power made from their cat-back exhaust system.

I have the cobb cold air intake, rear motor mount, as well as the accessport. I plan on upgrading both the intercooler and putting this exhaust on. My question is, is the stock intercooler good enough to upgrade my exhaust first on my 2013 ST?
After I had this installed, I drove a couple hundred miles, and then my check engine light came on. Is this normal?
I have Cobb accessport and cold air intake, no intercooler...which map do you recommend, leave it at stage 1? I want to get the most out of thevery exhaust, no plans for intercooler yet
