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."

The hype it did not live up to
Format: Paperback
I guess I expected more. I found it kind of boring and un inspiring. I enjoyed the food twist and even the characters, but it was very underwhelming. and I'm sorry about this review, because I really really wanted to love it.

A thoroughly-researched, thoughtful, and nuanced work about the 1692 Salem withcraft panic.
Format: Paperback
This graphic novel recounts the 1692 Salem (Massachusetts) witchcraft panic that engulfed Salem, Salem Village (now Danvers), and adjacent communities. About two dozen men and women were convicted and hanged, one was pressed to death (tortured) to try to force him to acknowledge the Court’s authority. That man was Giles Corey, aged 80. The book focuses on him, but it covers others among the accused and executed as well as on the judges, politicians, and other involved. (No so much on the accusers and their motives.). The narrative plays out chronologically with interstitial vignettes in which 19th Century literary figures Nathaniel Hawthorne and Henry Wadsworth Longfellow wander around Salem during the 1800s discussing the trials and their legacy. (Hawthorne lived in Salem for a time and was a descendant or the Court of Oyer and Terminer Judge Hathorne.). The work concludes with a chapter, More Wonders of the Invisible World, that follows how Salem developed economically up to the present day in which witchcraft-related Halloween tourism turns Salem town into arguably the least attractive “tourist attraction” on Cape Ann. (Do not skip this chapter, it is engrossing.) An extensive series of endnotes provide scholarly references and background information. The artwork veers back and forth between caricatures (the 17th century events) and realism (19th century and onwards). In both cases the line art is exquisite. The text includes quotes from transcripts of the trials and other contemporary documents as well as fictional dialog. Wickey worked on this book for more than a decade, and it shows in his thorough scholarship. This is, in all seriousness, Pulitzer/Eisner-level work. Wickey was born in Beverly and resides on Cape Ann. Most of us born and raised on the “North Shore” learn about the Salem witchcraft panic in high school -often as a cautionary tale about politics, spectral evidence, and what we would today call “lawfare.” I thought I knew a fair amount about the 1692 panic, but I learned something new with nearly every other page. I was especially glad to see Wickey cover now-debunked ergot-poisoning theory and that he dismissed the vile slander that some among the convicted and executed were actually witches. There’s nothing really “missing” from the book, though one wishes one could learn more about the fates of the accusers other than Ann Putnam. That their motives appear to have been “sport” is bone-chilling fully three centuries later. Read her "apology" years later and try not to think, "psychopath." At 500 plus pages, it's too long to read at one setting, but it is a pleasure to read at shorter intervals.

Masterpiece
Format: Kindle
It has been said that any work of literature should be gauged upon how much the work makes the reader think. Ben Wickey has certainly achieved this - in spades - as one of the “civilised” world’s most frightening episodes is revisited with respect and thoughtfulness on the human condition.
