COBB 591100 Focus ST 13-15 3" Stainless CatBack Exhaust System

Today we are installing COBB's 3" Stainless Steel Cat-Back Exhaust System on a 2015 Focus ST. One of the first mods most of our Focus ST customers make is replacing the restrictive factory exhaust. COBB is one of the biggest names in the ST market so we couldn't wait to hear how this system sounds.

Straight out of the box, COBB's cat-back exhaust is one of the nicest looking we have seen to date. A full 304 stainless steel construction, custom inline mufflers and dual 4" double wall stainless steel tips, resulting in a drone-free, aggressive exhaust note. Beautiful TIG welds seal all seams perfectly, resulting in zero exhaust leaks. CNC mandrel bent tubing creates the perfect fit for a no-hassle installation. COBB custom inline mufflers produce a sound unique to the COBB cat-back. The system was finished off with some gorgeous dual 4" slash cut, double wall tips feature the COBB logo which looks awesome on the back of any Focus ST.

Installation was simple but you will have to pic of a set of COBB Polyurethane Exhaust Hangers when installing on a 2015 because the factory exhaust has only 3 hangers and the COBB Cat-Back requires 4.
