Audi 8V RS3 Catted Downpipe

Upgrade your Audi RS3 8V with this 200-Cell High-Flow Catted Downpipe featuring full thermal heat shielding, engineered for drivers who want maximum performance without going fully catless. Designed for the 2.5 TFSI DAZA/CZGB engine, this downpipe delivers exceptional exhaust flow, quicker turbo response, and a deeper, more refined exhaust note — all while maintaining improved emissions compliance compared to a catless setup.

Constructed from premium 304 stainless steel and wrapped in multi-layer woven thermal insulation, this downpipe keeps radiant heat under control while retaining the structural integrity required for high-boost, high-temperature performance. The 200-cell sports catalytic converter reduces restriction significantly compared to the OEM cat, allowing the turbocharger to operate more efficiently while keeping exhaust odours and emissions more manageable.

Perfect for Stage 1+, Stage 2, and hybrid turbo setups, this downpipe balances performance, sound, and practicality — delivering big gains without the extreme characteristics of a completely catless system.

Key Features

200-Cell High-Flow Sports Catalytic Converter
Provides improved exhaust flow while maintaining better emissions control and reduced exhaust smell compared to catless designs.

Premium 304 Stainless Steel Construction
High-temperature, corrosion-resistant steel built to handle repeated heat cycles and high boost levels.

Full Thermal Heat Shielding
Multi-layer woven insulation reduces under-bonnet temperatures, protects nearby components, and maintains optimal engine bay safety.

Improved Turbo Efficiency
Reduced backpressure increases turbo responsiveness, delivering faster spool and sharper throttle response.

Precision TIG Welding
Strong, clean welds designed for durability under extreme thermal stress.

Direct Bolt-On Fitment
Designed specifically for the RS3 8V — bolts to factory mounting points with no modifications required.
