Genuine Cobra Exhaust. Part number: AU78BTP81.
Fits Coupe model only.
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 Audi TTS (Mk3) performance exhaust is made in 3’/76.2mm pipework and fit from the turbo backwards (turbo-back system), these parts replace the front pipe, centre and rear sections.
The sports cat exhaust option will enable you to pass a UK MOT emissions test or police road side checks. The de-cat sports exhaust option is sold for motorsport and off road use only and will NOT be able to pass a UK MOT emissions test or police road side checks.
The resonated exhaust option includes the centre silencer and has a subtle but sporty tone. This exhaust however, is also available as a non-resonated version (excluding the centre silencer) which is a louder option as it removes the resonated section.
Please Note: 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.
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.
All relevant fittings and gaskets are supplied.
The new Cobra Sport systems for the Mk3 TTS offer the best of both worlds producing a deeper exhaust tone than standard which becomes highly aggressive when under full load whilst maintaining a sophisticated improvement in tonality for everyday use.
The Cobra Sport development team have produced both valved and non valved systems for the Mk3 Audi TTS. The valued systems are designed with the valve housing welded directly into the exhaust system allowing the use of the OE motors through the direct electrical connection. All systems are available with the active exhaust valves removed creating a more intense, constant sound and power upgrade.
The Cobra Sport team were able to reduce the weight of the exhaust by an impressive 39% over the OEM system with the resonated 3′ non resonated cat back system weighing in at only 10.95kg compared to the original 17.95kg. The de-cat front pipe benefits from a 20% weight saving over standard weighing just 7.57kg.
Cobra Sport’s Sales Manager, Matt Thomas, explains ‘The sound we have managed to achieve from the Mk3 TTS is in line with the marque’s core values creating an unobtrusive and classy drive. The pitch perfect sound changes when under load increasing in volume and becoming more engaging with sound testing of the resonated cat back exhaust revealing a + 4dB increase on the 4,000 rpm test and + 9dB increase over the standard exhaust at idle. Those who require a more dynamic and aggressive exhaust tone can opt for the non-resonated turbo back system, which, with a de-cat, provides an all-round more involved and sportier upgrade whilst also opening up the opportunities for power gains for our tuning partners.’
Cobra Sport brings two decades of innovative design and unparalleled manufacturing expertise and are willing to back up their promises on quality, with a lifetime guarantee for customers who purchase the exhaust upgrade. Usual refinements that match the aspirations of the most demanding driver 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.
