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 system is made in 3"/76.2mm mandrel bent stainless steel pipework and fits from the catalytic converter section backwards (Cat-back) these exhausts replace the centre and rear sections.

The resonated exhaust includes the centre silencer and has a subtle but sporty tone. This exhaust however, 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.

Please Note:

The 'Valved' exhaust 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 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.

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 & 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."

Nice but…
Color: Blue Green Orange
Nice but not very sturdy and it comes rolled up so it’s difficult to get it to lay down for your dog.

Both my dogs LOVE find the treat game time!
Color: Orange Red Blue, Color: Orange Red Blue
Both my dogs have loved this for years. Both senior dogs - great fun activity for them and they really hunt for all the treats we hide! My little one usually wins and takes over the game board then uses it as a lounger after :-) It’s very interactive with different ways to hide treats and challenge the dogs. We’ve had it awhile and it has stood up to many uses and washes. Very easy to store and simply roll out when it’s game time. Highly recommend!

Perfect for snuffle dogs
Color: Blue Green Orange
If your pup/dog snuffles EVERYTHING or has a demanding intellectual stimulation food regime they set themselves this is for you! I have to roll out the mat above the floor to situation treats, but once it hits the floor my puppy is preoccupied for hours. She has so much fun sniffing through every element to find her treats. While the mat is easy to use I recommend rolling it back up immediately once most treats have been found to avoid chewing on the actual mat pieces (this could present a durability issue as the fabric is chewable). I use different flavored and textured treats throughout the mat as well as her normal dog food to keep her interested. Definitely worth the money if you have a snufflopogus puppy like I do.

My dogs are smiling!
Size: Small
I have 3 small dogs (ranging from about 10 lbs - 13 lbs). This dental toy was the perfect size. My dogs love it (with or without treats). It is durable, even after lots of chewing. I had bought another brand of the same type of toy and they bit off pieces in the first week. It really has made a difference in their teeth cleanliness and their breath is even fresher. Overall great value and my dogs love it!
