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.

My Favorite Face Mask for Hydrated, Glowing Skin
Scent: Collagen, Size: 4 Count (Pack of 1)
I’ve tried a lot of face masks over the years, but the BIODANCE Bio-Collagen Real Deep Mask has easily become my favorite. Every time I use it, my skin feels incredibly hydrated, smooth, and refreshed, and the results last much longer than I expected from a single mask treatment. One of the things I love most about this mask is how deeply moisturizing it is. After wearing it overnight, my skin looks noticeably plumper and feels soft and nourished. Instead of just giving a temporary boost, I’ve found that the healthy glow lasts well beyond the next day. In my experience, my skin maintained a radiant, hydrated appearance for nearly two weeks after use, which is something I haven’t experienced with many other masks. The hydrogel material feels comfortable on the skin and stays in place well throughout the night. When I remove it in the morning, my skin looks brighter, more refreshed, and noticeably more hydrated. I appreciate that this mask feels like a true self-care treatment rather than just another skincare step. Whether I’m preparing for a special event or simply giving my skin some extra attention, this is the mask I consistently reach for. The fact that it comes in a multi-pack makes it even better because I always like having one available when my skin needs a boost. Overall, this is one of the few skincare products that I continue to repurchase because I genuinely notice a difference. If you’re looking for a mask that delivers intense hydration, plumping benefits, and a beautiful long-lasting glow, I highly recommend giving this one a try.I’m

Instant Glass Skin!
Scent: Collagen, Size: 4 Count (Pack of 1)
I’ve tried SO many sheet masks and this collagen one is genuinely one of the best. My skin looked insanely hydrated, smooth, and glowy after just one use. It fit my face really well, stayed soaked the entire time, and didn’t leave that sticky feeling afterward. The next morning my skin still felt soft and looked brighter. Perfect before events or whenever your skin needs a reset. Definitely repurchasing!!

Absolutely amazing masks!!!
Scent: Collagen, Size: 4 Count (Pack of 1)
These masks are beyond amazing! I use one once a week and leave it on overnight after completing my p.m. skincare routine and wake up to smooth, plump, moisturized, and absolutely glowing!! I have extremely sensitive skin and eyes and these masks do not bother me at all. No burning in my eyes and no irritation of the skin. My deep wrinkles seem a lot less pronounced and some of my more fine lines almost disappear for 24 hours after using this mask. They are simple to use and adhere to the skin perfectly even after applying serums and moisturizers. Once the mask is completely absorbed and becomes clear it peels of the skin with ease. Based on the quality of these masks I am shocked by the low price, it is such a great value for your money. This Mask has become a staple in my skincare routine and I will continue to purchase these!!

instantly more hydrated + glowy skin
Scent: Collagen, Size: 4 Count (Pack of 1), Scent: Collagen, Size: 4 Count (Pack of 1)
I love this mask. It’s one of those products you can actually see a difference with right after using it. It really helps with: 1. Deep hydration – my skin feels plump and moisturized, not dry or tight 2. Smoother texture – it softens everything and makes my skin feel really smooth 3. Glow/brightness – gives that fresh, healthy glow without looking greasy How I use it: I apply it on clean skin (usually at night), leave it on as directed, and let it fully absorb before removing. I like using it when my skin feels dull or dry and want a quick reset. Overall, it’s super easy to use and makes my skin look more refreshed every time. Definitely a go-to for me.

Woke Up Glowing ✨ (But Sleeping In It Is a Stretch lol)
Scent: Collagen, Size: 4 Count (Pack of 1)
I was honestly impressed with this mask! It feels super soft, cooling, and refreshing while wearing it. The jelly texture makes it feel really hydrating and luxe, like a mini spa night at home. My skin looked smooth, plump, and GLOWING the entire next day after I took it off. Like… noticeably radiant. I also have sensitive skin, so I was a little nervous trying it at first, but I didn’t have any irritation or reaction at all. My skin felt calm, hydrated, and refreshed afterward. One thing I actually liked was that the mask was easy to customize a little. I have a nose piercing, so I just tore a small piece near my nose so it would fit comfortably without irritating it. The material held up perfectly, so that was a nice bonus for anyone with piercings or who just needs a better fit in certain areas. My only complaint is the “sleep in it” part of the instructions. I personally don’t see how that’s possible 😅 The mask stays pretty moist and jelly-like the whole time, so it felt uncomfortable to lay down in and I kept feeling like it would slide around. I ended up just wearing it for a while before bed instead. Overall though, the results were worth it and I’d definitely use it again for the glow alone!
