Wagner Tuning BMW E82–E93 N55 Catted Downpipe Kit
Improve exhaust flow on your N55-powered BMW with the Wagner Tuning Catted Downpipe Kit.
Designed as a performance-focused replacement for the factory downpipe, this 76mm stainless steel unit uses a 200 CPSI racing catalytic converter to reduce exhaust restriction while retaining a catted setup.
Wagner Tuning part number:
500001005
76mm Catted Downpipe
The Wagner Tuning N55 downpipe is designed to improve exhaust gas flow directly after the turbocharger.
Key features include:
- 76mm diameter
- Stainless steel construction
- 200 CPSI racing catalytic converter
- No pre-catalyst
- Improved exhaust gas flow
- Reduced exhaust back pressure
- Reduced thermal load on the turbocharger
- Performance-focused design
Improved Turbocharger Efficiency
The factory downpipe and catalytic section create restriction immediately after the turbocharger.
Replacing them with a freer-flowing design can help exhaust gases leave the turbocharger more efficiently, supporting:
- Reduced back pressure
- Improved turbo response
- Better exhaust flow
- Reduced thermal load
- Increased performance potential
Performance-Focused N55 Upgrade
A downpipe is one of the key exhaust-side upgrades for the turbocharged N55 platform.
This Wagner Tuning kit is well suited to:
- Fast-road builds
- Track-focused cars
- Higher-performance N55 setups
- Cars fitted with upgraded intercoolers
- Other supporting airflow modifications

Important Road-Use Notice
Although this downpipe uses a catalytic converter, it should not automatically be assumed to be road legal or MOT compliant.
Local emissions and road-use requirements should be checked before installation.
A DME warning or emissions-related fault may also occur depending on vehicle configuration.
Catalytic Converter Notice
Wagner Tuning states that its performance catalytic converters are intended for use on vehicles with standard engine management for performance optimisation.
Use alongside ECU tuning or engine conditions that create excessively rich or lean mixtures may affect catalyst durability and warranty coverage.
Professional Installation Recommended
Professional installation is strongly recommended.
All exhaust connections, lambda sensor fittings, clearances and fasteners should be checked carefully after installation.
