Maximize Turbo Spool & High-Flow Performance — CEES Audi S3 8VS 2.0T Downpipe Exhaust System
Precision-engineered specifically for the Audi S3 2.0T TFSI (MQB Platform / 8VS Sedan & 8V Chassis / 2014–2023), this premium Downpipe Exhaust System eliminates factory exhaust backpressure right off the turbocharger. Designed to dramatically enhance exhaust gas velocity, sharpen throttle response, and unleash an aggressive, throaty sport exhaust note, it is available in both Catless (Track/Race) and High-Flow Catted (100 / 200 / 300 Cell) configurations.
🚀 Engineering Highlights
- Optimized High-Flow Turbo Velocity: Smooth mandrel-bent oversized stainless piping removes severe factory catalytic restrictions directly at the turbo turbine exit, significantly reducing backpressure and accelerating boost spool.
- Race-Proven High-Flow Catalyst & Catless Options: Available with premium high-flow metallic substrate catalytic converters (100, 200, or 300 cell density) for balanced exhaust flow, or a full catless test-pipe configuration for unrestricted motorsport performance.
- Master-Tier Hand-TIG Craftsmanship: Precision fixtures and skilled TIG welding guarantee ultra-smooth internal airflow transitions, zero pipe deformation, and lasting structural integrity under intense exhaust heat.
- 3D Scan Direct Bolt-On Precision: Developed from 3D laser underbody scans to ensure direct alignment with factory turbo v-band flange connections, OEM mounting brackets, and downstream catback piping.

FAQ
1. What is the difference between Catless and High-Flow Catted downpipes?
The Catless option removes all catalytic restriction for maximum exhaust velocity, raw acoustic aggression, and track performance. The High-Flow Catted options (100, 200, or 300 cell) utilize high-durability metallic substrate catalytic converters to deliver substantially increased flow over restrictive OEM units while reducing raw exhaust odor and maintaining clean exhaust velocity.
2. Will installing a downpipe trigger a Check Engine Light (CEL)?
High-flow and catless downpipes alter post-catalytic exhaust gas readings. To ensure trouble-free operation, all orders include a complimentary O2 sensor CEL fix spacer designed to isolate secondary oxygen sensor readings. For maximum power output and optimized fuel mapping, Stage 2 ECU tuning is recommended.
3. Is this a direct bolt-on installation?
Yes. The exhaust features 100% bolt-on installation allows a return to stock at any time. (Reuses factory outlets). It connects directly to the OEM turbo outlet and mates smoothly to either the factory catback exhaust or CEES valved sport exhaust system.
4. Are you a direct manufacturer?
Yes — CEES Exhaust is a direct manufacturer based in Guangdong, China. We build our downpipes in-house with strict quality control, high-grade T304 stainless steel, and precision jigs for factory-direct reliability.
