Cobra Sport Review

The Cobra Sport development team took delivery of the Mk8 Fiesta ST soon after its UK release keen to begin development on an exciting new range of Performance Exhaust upgrades. The new exhaust systems will be initially available in Gasoline Particulate Filter (GPF) Back configuration and includes the motorised exhaust valve.

The bore size of the Cobra Sport exhaust has been increased to 3″ (76.2mm), which is unique in the market providing the greatest upgrade in terms of performance, flow rate and sound levels.

In order to keep the use of the drive select modes, the Cobra Sport exhaust range has been designed with the inclusion of the active valve to help regulate exhaust tone at low speeds and keep the tone differences between drive modes.

Matt Thomas, Sales Manager at Cobra Sport says ̢The new 1.5 Litre EcoBoost engine is unknown in the market so we were keen to immediately improve the sound produced by the 3 cylinder engine. Our development team worked hard to ensure the 3″ pipework was a perfect fit as we felt Fiesta owners would be looking to upgrade to a full 3″ performance exhaust once the tuning capabilities of the engine are explored further by our extensive dealer network. Templates and preliminary drawings have been produced to enable us to create the full turbo back (with de-cat/sports cat downpipes) and GPF delete exhaust options once the tuning software becomes available in the coming months.”

The Cobra Sport Mk8 Fiesta ST exhausts are finished with twin 3.5″ highly polished stainless steel or ceramic black slash cut tailpipes engraved with the Cobra Sport logo along with a 3.5″ Carbon Fibre tip option.

As with all Cobra exhaust developments, power increases, sound improvements and manufacturing quality are top of the priority list during development. Superior TIG welding techniques during the manufacturing process set the Cobra Sport exhausts apart from the competition. The levels of quality achieved enables us to offer a lifetime guarantee on all exhaust systems which provides the ultimate peace of mind for the customer.
