Cobra Sport Ford Focus ST (Mk4) Cat Back Exhaust

Requires ECU reflash/remap

Cobra Sport performance exhausts enhance the sound, looks and quality of your vehicle giving you the ultimate driving experience. Our sports exhausts range is fully guaranteed to give you assurance of our quality.

This Ford Focus Mk4 ST cat back performance exhaust is made in 3″/76.2mm pipework and fits from the Catalyst section backwards (Cat-back) replacing the GPF, centre and rear sections.

This non-resonated exhaust makes the system louder as it excludes the centre silencer and therefore, has a sportier exhaust note. This exhaust however, is also available as a resonated version (including centre silencer) which is a quieter option.

IMPORTANT: this exhaust removes the GPF filter and will require engine tuning at time of fitment to cancel the EML light.

Fitment to GPF equipped models is for motorsport and off road use only*

Cobra Sport Exhausts provide the performance exhaust solutions for the Mk4 Focus STs raced by the MB Motorsport accelerated by Blue Square and Motorbase Performance teams in the 2021 Kwik Fit British Touring Car Championship. This technical partnership allows us to test our products on track at the highest level of British Motorsport. The experience gained from the competitive track environment is fed back into all of our road going performance exhaust systems.

Press Release

The Ford Focus ST has long been a favourite amongst hot hatch fans, especially in the UK, ever since the launch of the Mk1 ST170 back in 2002. The Mk2 ST moved Ford’s hot hatch game on even further in 2005 when they fitted it with a thundering 2.5 5-Cylinder engine. And in 2012, despite losing a cylinder and half a litre of capacity to its predecessor, the Mk3 still sold in the thousands.

Every generation of Focus ST has had seemingly limitless tuning potential thanks to their horsepower-hungry engines and playful handling characteristics. Cobra Sport have enjoyed enormous success in this field, with their performance exhausts for both the Mk2 and Mk3 Focus STs being amongst the best-selling systems in the market. Aiming to replicate this success, Cobra Sport are proud to announce their latest product range for the Ford Focus ST Mk4. Over the past few months, their Research and Development team have been hard at work developing an extensive range of performance exhaust systems that will cater to the needs of any fast Ford enthusiast.

Also available in the range is Cobra Sport’s Cobra’s unique ‘Venom’ range. For those who want a further improve sound levels, the Venom exhaust removes the rear silencer to offer the biggest sound increase whilst keeping a sporty exhaust tone(+8.5db in GPF-Back Venom configuration).

Like all Cobra Sport exhausts, the Mk4 Focus ST systems are TIG-welded from high-quality T304 stainless steel and the mandrel-bent pipework is a full 3in (76.2mm) in diameter for maximum sound and tuning potential.

With over 25 years in the performance exhaust industry, each Cobra Sport exhaust system is designed, manufactured and tested in Sheffield, the heart of the UK steel industry. Cobra Sport utilise TIG-welding techniques to ensure a flawless finish and quality that you can rely on.

Excellent sunscreen for daily sun protection...
This is a great sunscreen for the "light" days in the sun. I layer my skincare (serums, creams, then sunscreen) before I apply my makeup. Sunscreen is always the last step before I apply my makeup. Other brands have been known to "bead up" under my makeup through out the day, or have a white cast to them. This does not do that. It doesn't leave a white cast, or residue of any kind on my skin. It is lightweight to the point of being weightless right after application. It is incredibly moisturizing on my dry skin as well, which I LOVE! Love the ingredients too for everyday use! The only downside to this sunscreen is it isn't strong enough to protect my skin on days I am in the sun a lot and cannot reapply every hour, or so. I noticed a couple of stubborn brown spots pop up after a couple hours in direct sunlight. I didn't burn, but I did get a tan on my face I was hoping to avoid. All in all, This is my favorite sunscreen I use when I am running to-and-fro, but not the sunscreen I will use at the ball field, or a day at the beach.

A little pricey but worth it
I LOVE THIS SO MUCH. I have really sensitive skin and eczema, and am allergic to scented liquid soaps, detergents and creams. I got a sample of this in a subscription box, and fell in LOVE after I tested just a little on my hand at first. Now I've ordered multiple time, and even shipped some to my mom! It feels luxurious but also fresh and natural on your face, I put it on as a moisturizer, hit some concealer under my eyes, swipe some mascara on and am good to go - it feels like a whole skin-care routine in one go. The size is a little small for the price, but it's light, non-irritating, and refreshing. I think it's definitely worth it if you have sensitive skin and want sun protection without a load of chemicals on your face. I put a picture of what it looks like on my hand reflected in some light - it's slightly greasy at first, but it dries nice and soft afterwards, I still feel like my pores can breathe. I usually don't write product reviews, but after I ordered my 3rd batch I felt I should share. *One other thing to note - make sure you read the label if you want the specific scented one, I accidentally ordered the unscented one when I wanted the cucumber because the packaging looks the same and the label is in the scripty font and I missed it when I made a rushed order.

Great for sensitive skin
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
I usually have problems with fragrance in almost any face cream or sunscreen, and my skin reacts very easily, so I’m always careful with what I use. I tried the COOLA Organic Face Sunscreen SPF 50 Sunblock Lotion (Fragrance Free) and I’m honestly impressed. It feels very light on the skin, doesn’t irritate my face at all, and finally a sunscreen that doesn’t have that strong smell that usually bothers me. It absorbs well, works great under makeup, and gives good daily protection without feeling greasy. If you have sensitive skin or issues with fragrance like I do, this one is definitely worth trying.

Love this sunscreen
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
I would love to buy again, but I go through sunscreen, I have to find a little less expensive one. No burn, dewy not greasy look. Great for mature skin. No fragrance, works well, melts right in the skin. I do love this product and the spray too!

Light and works with no eye stinging.
Scent: White Tea, Size: 1.7 Fl Oz (Pack of 1)
I love this sunscreen. I wear co tact’s and most sunscreen ends ups burning my eyes. This does not! It has a nice cucumber smell and it’s not sticky or heavy. By far the best face sunscreen that’s light, smells nice, doesn’t burn my eyes and works.
