Audi TTS Quattro Coupe stainless rear exhaust upgrade that transforms sound and style while keeping the catalyst in place. Built from premium 304 stainless steel with beautiful TIG welds and mandrel bends, this UK-made system delivers a richer soundtrack, sharper aesthetics and long-term durability. We have fitted plenty of these at MJ Modifications and our customers consistently praise the fit, finish and tone.

Real performance pedigree
Developed on the track and released for the road. Cobra Sport’s full development on the TTS has shown that with a complete turbo-back setup including a de-cat and an appropriate ECU recalibration, the platform can deliver significant gains. Their testing reported an increase of around 35 percent in BHP and 27.5 percent in torque with that full configuration. This rear system is the ideal foundation for staged tuning while maintaining everyday usability.
