Wagner Tuning part number:

76mm Catless Downpipe

The Wagner Tuning N55 downpipe features a 76mm diameter and catless construction for maximum exhaust flow.

Key features include:

• 76mm stainless steel construction
• Catless design
• No pre-catalyst
• Improved exhaust gas flow
• Reduced exhaust restriction
• Reduced thermal load on the turbocharger
• Designed for motorsport and performance applications

Improved Turbocharger Efficiency

The factory catalytic section creates restriction immediately after the turbocharger.

Replacing it with a freer-flowing downpipe can help exhaust gases leave the turbocharger more efficiently, supporting:

• Reduced back pressure
• Improved turbo response
• Better exhaust flow
• Reduced thermal load
• Improved 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:

• Motorsport builds
• Track cars
• Higher-performance N55 setups
• Cars fitted with upgraded intercoolers
• Other supporting airflow modifications

Vehicle Fitment

Designed for selected N55-powered BMW E-Series models including:

• BMW E82 135i

Exact engine and production-year compatibility should be confirmed before ordering.

Important Road-Use Notice
