The new Focus RS is a car we were keen to get into the workshop as soon as the preliminary details were released last year and are thrilled to have now completed development work so soon after the release date.
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 2016 Focus RS features an all-wheel drive system with dynamic torque vectoring control matched with the new 2.3-Litre EcoBoost engine producing over 350 PS which also appears in the new Mustang.
The EcoBoost engine is fitted with a twin-scroll turbo matched with uprated air intake components. We identified a number of limitations with the standard Focus RS exhaust system and have looking to smooth the pipework to give the engine maximum room to breathe. As standard the exhaust emits a more subtle than expected tone which we have improved upon with all system configurations.
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 systems. The valued systems are designed with the valve housing welded directly into the system allowing the use of the OE motors through the direct electrical connection. All systems are available with the active valve removed creating a more intense, constant sound and power upgrade.
These systems include a specialised housing plate which will allow the valve motors to remain connected to the vehicle electronics but not form part of the exhaust, therefore allowing the use of all drive modes.
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) 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".
