1. Will a performance exhaust cause a "Check Engine" light on my Audi A3?
A cat-back exhaust system will not trigger a CEL as it sits after the primary sensors. However, installing a high-flow downpipe or removing the catalytic converter can trigger efficiency codes. For these upgrades, we recommend a Stage 2 ECU tune to optimize performance and keep the dashboard clear of warning lights.
2. What is the benefit of a 3-inch system over the factory exhaust?
The factory Audi A3 exhaust is designed for maximum noise suppression, often using restrictive chambers and smaller diameters. A 3-inch mandrel-bent system significantly reduces backpressure, allowing the turbo to spool faster and providing a more aggressive, sporty soundtrack.
3. Do you offer replacement DPFs for Audi A3 diesel models?
Yes. We carry Redback Enviro DPFs specifically for the Audi A3 8P and 8V diesel range. These are designed as direct bolt-on replacements that meet or exceed OE performance requirements, restoring fuel efficiency and engine power.
4. Can I control the volume of the exhaust from inside the cabin?
By choosing a system equipped with XForce Varex technology, you can. The electronic internal valve allows you to adjust the sound level on the fly—keep it quiet for the early morning commute and open it up for a deep, throaty roar on the open road.
