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 Focus RS (MK3) 2.3L EcoBoost 350PS performance exhaust is made in 3"/76.2mm pipework and fits from the turbo backwards (Turbo back system) this exhausts replace the front pipe, standard catalyst, centre and rear sections.

The high flow sports cat version will enable you to pass a UK MOT emissions test or police road side checks. This exhaust is also sold with a de-cat option for motorsport and off road use only and will NOT be able to pass a UK MOT emissions test or police road side checks.

The resonated exhaust includes the centre silencer and has a subtle but sporty tone. This exhaust is also available as a non-resonated version which is a louder option, as it excludes the centre silencer and therefore, has a sportier exhaust note.

All relevant fittings and gaskets are supplied. (Except turbo gasket).

Please Note:

The 'Valved' exhaust option retains the use of exhaust valves. When switching drive modes (e.g. Eco to Race mode) your exhaust tone will continue to swop from quieter to louder tones as before.

The 'Non-Valved' exhaust option removes the use of exhaust valves. When switching drive modes (e.g. Eco to Race mode) your exhaust tone will not change from quieter to louder as before. Using a Non-Valved exhaust will not harm the running of your vehicle, you will simply not have exhaust sound options, however the Cobra Sport exhaust has been designed with this in mind.

Some of the fitted exhaust images may show alternative parts.

Press Release

The Cobra Sport development team have created a full range of exhaust systems to take the RS to the next level through precision design and technology, allowing for increases in power and creating a sound track worthy of the future classic RS. The mandrel bent T304 Stainless Steel pipework has been designed to give the engine maximum room to breathe. The new Cobra Sport systems produce a much deeper exhaust tone than standard which becomes highly aggressive under load to produce a pitch perfect soundtrack along with the trademark gargles, crackles and pops expected from the Focus RS.

The Cobra Sport systems deliver a significant weight saving over standard. Testing of the non resonated turbo back system with de-cat resulted in a 13% reduction in weight over the OE system's 24.3kg. On offer are a full range of configuration options including a cat-back exhaust system along with de-cat and sports cat front sections to form a full turbo back replacement. Taking development for the RS a step further, Cobra Sport have created a Venom exhaust system (with resonated centre) which produces a completely unique sound track. This system matched with the OE standard catalyst recorded the highest sound levels in our tests registering 101.5db (+22.8db) on the 4,000rpm static test.

The Cobra Sport development team have produced both valved and non valved sports exhausts for the Focus RS. The valved exhaust retains the use of O/E exhaust valves, so when switching drive modes (e.g. Eco to Race mode) the exhaust tone will continue to change from quieter to louder tones as before. The non-valved option removes the O/E exhaust valves altogether, and thus removes the drivers option of having various exhaust tones at the press of a button, however the non-valved Cobra Sport exhaust has been designed with this in mind.

Matt Thomas, Sales Manager at Cobra Sport says "The many system configuration have a unique blend of sound and tone characteristics. The most dynamic upgrade was the full non resonated turbo back with de-cat which completely altered the sound of the car."

"At Idle this system only increased the decibel level by +12.5db but once under load the system comes to life, producing a pitch perfect tone at a level of 100db (+21.3db) on the 4,000 rpm sound test to match the aggressive RS styling. The dual tailpipes sit neatly with the stylish rear diffuser. We were keen to make the most of the dual exit design and are excited to offer a choice of bold 4.5" (114.5mm) highly polished slash cut stainless steel tailpipes."

Best fun indestructible toy
Color: Crinkle Duck (Yellow), Size: Large
Truly indestructible no matter how much our oittie tries. She has owned it for three months works at destroying every day with no success. She carries it everywhere. Best purchase for chewer, more fun than the popular rubber heavy duty toy. Do not hesitate your pup will thank you for this fun distraction.

My dog loves this toy!
Color: Bunny (Gray), Size: Large, Color: Bunny (Gray), Size: Large
High quality, big toy, perfect for a medium to large size dog. After a few months of serious chewing I had to buy another one, but well worth the money! Rocky loves it.

Great toy but if your dog is an aggressive chewer, please think twice.
Color: Crinkle Chicken (Brown), Size: Large
I received this on May 23rd and on June 8th, after playing with this thing every day, our recently acquired 36 lb dog finally ripped it open and got out all the plastic and the squeaky part. Lily Belle will miss you, chicken. Lily loooooved this toy! She'd toss it in the air, chew on it, pull it with her teeth etc. but as much as she loved it, we won't replace it. It's just not durable enough for her. If your dog is an aggressive chewer, you might want to try a different toy. I hate that this lasted just a smidge over two weeks because Lily seemed to truly enjoy this toy. RIP, squeaky chicken!

Great Value Toy
Color: Crinkle Duck (Blue), Size: Large, Color: Crinkle Duck (Blue), Size: Large
This toy has been one of my dog’s absolute favorites. He gets excited every time he sees it and will carry it around the house, toss it in the air, and keep himself entertained for a long time. The shape and texture seem perfect for him, and it quickly became one of his go-to toys over everything else in his basket. What I really like is that it holds up reasonably well for the price. It’s definitely not indestructible, and after a lot of play, it will sometimes start to rip—usually around the feet first since that’s where my dog tends to grab and chew the most. But honestly, considering how affordable it is, I don’t mind replacing it when needed. It’s inexpensive enough that rebuying feels worth it because he genuinely loves it that much. I’d rather keep buying a toy he is obsessed with than spend more on something that just sits untouched. It’s fun, cute, and keeps him happy, which is what matters most. Overall, I’d definitely recommend it for dogs who love plush toys and playful chewing.

Best affordable squeaker toy
Color: Crinkle Chicken (Brown), Size: Large, Color: Crinkle Chicken (Brown), Size: Large
my dog is obsessed with this toy, this has became his new comfort toy and after having this for about four months the legs are falling off but it’s very durable. The squeaker also moved from the head of the chicken to the body of the chicken but that’s after it was played with every single day. I love that it has two squeakers and it’s the perfect toy for my dog.
