Press Release

The Ford Focus ST Mk3 was always on the agenda to lend itself to another of Cobra Sports exhaust Venom upgrades, due to the massive success of the marques predecessor.

The Cobra Sport development team again recommended a 3″å� bore system in order to gain the best results with regards to both power and sound. The final venom development is available in cat-back only option. Independent testing on the cat-back system gave a healthy power increase to 261.5bhp with an 8.27% increase in torque (from 254 ft per lb to 275 ft per lb).

There is also an exceptional weight advantage, with the Cobra Sport Venom exhaust being 33.5% lighter than the original equipment cat back system. The new Focus ST Venom system is designed for those seeking a more powerful sound quality and this exhaust does a come with a ‘Track day use only’å� warning.

After sound testing with the standard O/E front parts the Cobra Sport Venom system was registering a sporty 93.2 dB level compared to the standard 72.1 dB.
