The ARM N54 Turbo Outlets increase power by improving airflow right after the turbos — the first component of the charge-air system. ARM enlarges this piping to 2", a 100% increase over the 1" stock outlets, for more power and better low-end torque.

Highlights

• 2" aluminum construction (100% larger than the 1" OEM outlets).
• Gains of up to 25 whp.
• Improved low-end torque.
• T6061 aluminum.

Construction

T6061 aluminum with an enlarged OEM-style CNC-machined V-band connection that fits OEM-style or upgraded turbos using the 2" OEM connection. Where the OEM outlets keep the two turbos' air channels separate, the ARM outlets merge the charged air upstream before the FMIC for better flow. A 5-layer silicone coupler (with two T-bolt clamps) joins the sections and resists expansion under high boost.
