ARM BMW 335XI CATLESS DOWNPIPES - N54 AWD N54DPAWD
HIGHLIGHTS
• Improved Exhaust Sound
• 304 Stainless Steel
• Perfect Fitment
PROFILE
Take your N54 powered BMW 335xi to the next level with ARM Motorsports 3" catless downpipes.
The ARM N54 AWD catless downpipes eliminate the restrictive OEM converters on the stock downpipes allowing the exhaust to flow more freely, increasing power and torque. Because higher boost levels generate more heat, the ARM 335xi catless downpipes allows your AWD N54 to run boost settings of Stage 2 tunes and beyond.
CONSTRUCTION
The ARM 335xi catless downpipes are designed with 3" stainless steel construction to optimize exhaust flow off the turbochargers and reduce to 2.5" to match up perfectly to the OEM midpipes. Our 335xi downpipes are designed specifically to fit your AWD N54 platform.
Each downpipe has two O2 sensor bungs so the factory BMW O2 sensors can be remounted allowing the ECU to continue to monitor the air/fuel mixture via the exhaust. Because these downpipes are a catless design, an ECU tune or CEL fix will be needed to avoid a CEL from displaying on instrument panel.
