One of the great things about the Cobb Cat-Back for Focus ST is that it’s one of the Focus ST exhaust systems that’s kind of in the “goldilocks” range of being just right, aggressive enough that you hear it more, but not loud enough that it drones and whatnot. It’s a rather nice sound. Check it out how it sounds in this video comparison on another Focus ST.
The mudflaps really make the car much more aggressive looking, not to mention they also help keep the sides and rear of the car cleaner. Black cars are incredibly hard to keep clean and as you can tell in the photos, Martin’s Focus ST is immaculately clean.
Of course, the Cobb 3in Cat-Back Exhaust for Focus ST isn’t the only mod to the exhaust system, the Milltek Catless Downpipe for Focus ST EcoBoost 2.0T is the other critical requirement for running a full “Stage III” tune, and Milltek’s decat downpipes are as beautifully finished as these Cobb tips.
On the interior, a Cobb Knob for Focus ST makes shifting fast and positive and the arctic camo-faced Cobb AccessPORT V3 has been loaded with a custom PROTUNE written by COBB TUNING SoCal, making the gains much more dramatic. No wonder Justin was impressed enough by this car to go out and buy a Focus ST of his own!
Under the hood, the COBB logos clue you in to what bits of the intake have been replaced by the Cobb CARB Approved Cold Air Intake for Focus ST, which enhances power and response as well offering a bit more of that “turbo” sound, and a mountune Uprated Boost Pressure Valve prevents the loss of boost that normally occurs through the leaky OEM BPV.
Since the Cobb Cold Air Intake for Focus ST is CARB approved – see that little sticker on the airbox? The intake system on there is totally smog legal, so no smog shop in CA can hassle you over the intake, which is great piece of mind.
