Flashark 3" Catless Downpipe for 2012–2015 Audi 2.0T A3 A4 A5 A6 Q3 Q5 S3 TT TTS

A: This kit fits selected 2012–2015 Audi A3, A4, A5, A6, Q3, Q5, S3, TT, TTS and allroad models equipped with a confirmed 2.0L inline-4 turbocharged gasoline engine. Fitment varies by model and year, so check the complete Fitment table and use the vehicle selector before ordering.

A: Yes, it fits the Quattro applications specifically listed in the Fitment table, including selected A3 Quattro, A4 Quattro, A5 Quattro, A6 Quattro, Q3 Quattro, TT Quattro and TTS Quattro models. A Quattro badge alone does not confirm fitment—the year, model, engine and original exhaust configuration must also match.

A: No. Audi used different engines, turbocharger connections, chassis layouts and exhaust configurations across different models and years. Only order this product if your exact year and model appear in the Fitment table.

A: This Audi-specific page is intended for confirmed 2.0T gasoline applications. Do not order it for a TDI diesel model unless Flashark support separately confirms compatibility using your vehicle information or VIN.

A: This is a catless downpipe. It does not contain a catalytic converter and replaces the factory downpipe and catalytic-converter section. A high-flow catalytic converter is not included.

A: It may. Removing the factory catalytic converter can cause the ECU to detect reduced catalyst efficiency and store an emissions-related fault code. Flashark does not guarantee that the product will operate without a check-engine light on every Audi application.

A: An ECU tune is not physically required to install the downpipe, but compatible calibration may be recommended to optimize performance after changing exhaust flow. Tuning requirements vary by engine version, ECU software, turbocharger and supporting modifications. Consult a qualified Audi or Volkswagen Group tuner before installation.

A: There is no single guaranteed horsepower increase. Results depend on the engine version, turbocharger, ECU calibration, fuel, intake, intercooler and the rest of the exhaust system. The 3-inch catless design primarily reduces exhaust restriction and supports improved turbo response and tuned performance.

A: Expect a deeper and louder exhaust note, more noticeable turbo sound and increased volume under acceleration. The exact result depends on the Audi model and whether the vehicle uses the factory or an aftermarket cat-back exhaust. A catless system can also produce more exhaust odor.

A: It may not. This product removes the factory catalytic converter and can fail a visual, tailpipe or OBD-II emissions inspection. It is intended for off-road, track or competition use where permitted. Check applicable regulations before purchase and installation.

A: It is designed as a bolt-on replacement for the confirmed applications. Installation still requires removal of the factory downpipe, correct positioning of the oxygen sensor and proper alignment with the remaining exhaust system. Vehicles with aftermarket turbochargers, custom exhausts or previously modified piping may require an adapter or additional fabrication.

A: The included connector pipe is designed to connect the downpipe to the original exhaust layout on the confirmed applications. If the vehicle has an aftermarket cat-back, custom piping or a different turbocharger, compare the connection diameter and layout before installation.

A: The package includes one catless downpipe section, one connector pipe and one exhaust clamp. Only the components shown in the product images are included. Replacement factory gaskets or fasteners are not included unless specifically pictured.

A: Installation is possible for an experienced technician with suitable lifting equipment and exhaust-system tools. Because turbocharger access and underbody clearance vary between Audi models, professional installation is strongly recommended. Inspect the completed system for leaks, rattles and contact with surrounding components.

A: Returns generally require the product to remain new, uninstalled and in its original packaging. Compare the supplied downpipe with the original part and confirm vehicle fitment before beginning installation. Review Flashark’s current return policy for complete eligibility requirements.
