Unlock the true performance potential of your BMW N26-powered vehicle with the ARM Motorsports N26 Catless Downpipe. The factory N26 downpipe contains a large, restrictive catalyst that significantly limits exhaust flow—choking performance and preventing you from safely upgrading to a Stage 2 tune.
The ARM N26 Downpipe is the ideal first hardware upgrade for any N26 owner. By reducing back-pressure and eliminating the restrictive OEM catalytic converter, this downpipe enables significant power gains, sharper turbo response, and a more aggressive exhaust note. Whether you're running a stock tune or upgrading to Stage 2+, this downpipe is essential for maximizing output and drivability.
PERFORMANCE GAINS
Testing on our in-house BMW 328i showed the following improvements:
-
+17whp / +25wtq with Stage 1 tune
-
+30whp / +38wtq total gain with Stage 2 tune over Stage 1
In addition to performance benefits, you'll experience a deeper and louder exhaust note—especially noticeable under full throttle. Pairing the ARM Downpipe with an upgraded midpipe or cat-back exhaust delivers an even more aggressive tone.
CONSTRUCTION & DESIGN
Crafted from mandrel-bent SS304 stainless steel, the ARM N26 Downpipe is engineered for durability and long-term performance. It begins with a 4.0" CNC-machined v-band flange at the turbo outlet and smoothly tapers to a 2.5" outlet to perfectly mate with the OEM midpipe using the factory clamp.
Features include:
-
Precision TIG welds
-
Two O2 sensor bungs for OEM sensor compatibility
-
Direct bolt-on installation with OEM and most aftermarket exhaust systems
RECOMMENDATION
With the increased power and boost potential this downpipe unlocks, intake air temperatures (IATs) may rise. We recommend upgrading your intercooler to maintain performance. The ARM F-Series FMIC is a perfect match for this setup.
