Wagner Tuning BMW F-Series N55 Catless Downpipe Kit -6/13
Product Description
The Wagner Tuning N55 Catless Downpipe Kit is a high-flow, motorsport-focused exhaust upgrade designed for early-build BMW F-Series N55 models produced up to June 2013.
By removing the factory catalytic converter, this downpipe eliminates one of the largest restrictions in the N55 exhaust system — maximising exhaust flow, improving turbo spool and unlocking stronger mid-range performance.
This is the ideal downpipe for drivers running Stage 2 tunes, hybrid turbos or track-focused setups where maximum performance and response are the priority.

Why Choose the Wagner N55 Catless Downpipe (–06/2013)
The early N55 catalytic converter is highly restrictive under increased boost, limiting both turbo efficiency and top-end power.
Wagner’s catless design removes this bottleneck completely, providing:
-
Much quicker turbo spool
-
Stronger mid-range torque
-
Sharper throttle response
-
Lower EGTs for improved engine safety at high load
Built with TIG-welded stainless steel and engineered for OE-level fitment, the Wagner catless downpipe is a proven upgrade for early N55 owners chasing maximum performance.
