Cobra Sport has managed to achieve a power boosting system for the TTS which delivers impressive results in both bhp and torque, yet also combines with the marques core values of providing a classy, quietly sporty drive.

The OE system was replaced with a 3”/76.2mm bore upgrade and with the top conversion, a complete turbo back system including a de-cat (re-map required), the power gains are substantial, providing an impressive 35% increase in BHP and torque results showing a 27.5% increase.

Tailpipe finishes are available in a choice of traditional highly polished stainless steel or matt black in quad 3”/76.2mm or a more defined 3.5”/88.9mm, these tailpipes are a round design and shaped to fit nicely into the smooth lines of the TTS, subtly hinting at the performance upgrade underneath the car.

Matt Thomas, Sales Manager at Cobra Sport offers his verdict on the TTS upgrade “The fantastic power gains achieved with this car are quite astonishing when you consider that only a fractional decibel level increase was recorded, this truly allows for customers to benefit immensely from a Cobra Sport system without it interfering with the day-to-day driveability of the car”.

As always Cobra Sport are willing to back up their promises on quality, with a lifetime guarantee for customers who purchase the exhaust upgrade. Usual refinements include, hand finishing using advanced TIG welding techniques and all Grade 304 stainless pipework being formed expertly on CNC Mandrel bending machines, which ensures the smoothest of gas flow, with precision jig manufacturing to ensure a perfect fit.
