Wagner Tuning BMW F-Series N55 Catless Downpipe Kit 7/13+

High-flow de-cat turbo outlet for BMW N55 F-series

Unlock sharper spool, stronger mid-range and a more aggressive soundtrack with this performance de-cat down pipe for BMW N55 engines. Precision CAD designed and manufactured from 1.4301 stainless steel (SS304), this race-spec turbo outlet replaces the restrictive factory section to cut exhaust backpressure, reduce turbine heat load and free up power and torque on tuned and stock cars alike.

We fit these regularly at MJ Modifications and customer feedback has been consistently excellent. Fitment is hassle-free thanks to the direct-swap design, and the transformation in response and flow is exactly what N55 owners are looking for when moving toward Stage 2 tuning, remaps or turbo-back upgrades.

Why choose this performance down pipe

• Lower exhaust restriction for quicker turbo response and stronger pull
• Reduced thermal stress on the turbocharger under sustained boost
• Bolt-on replacement for the factory unit for easy installation
• Two lambda sensor ports for OEM O2 sensors
• Durable 1.4301 (SS304) stainless construction
• Connection diameter: 118 mm
