Charge Pipe Kit for BMW 335i 335xi 335is (2007-2013) Turbo Outlet

Delete the most restrictive part of your N54's boost system and finally let those turbos scream.

High-Flow Aluminum Turbo Outlet Charge Pipes for 2007-2013 BMW 135i/335i/Z4 (N54 Twin Turbo)

If you are modifying an N54, you know the struggle of the factory "pancake" pipes. To fit the twin-turbo setup around the steering rack, BMW crushed the factory turbo outlets down to a restrictive sliver—sometimes less than 1 inch in diameter. This creates a massive bottleneck that chokes airflow, increases backpressure, and forces your turbos to work harder just to hit target boost.

This 2-inch Aluminum Outlet Kit replaces those flattened factory tubes with full-diameter, mandrel-bent piping. By maintaining a consistent 2-inch diameter from the turbo compressor housing to the intercooler, we eliminate the restriction that kills top-end power. Whether you are running stock turbos or upgraded hybrids (Pure, RB, VTT), these outlets are the key to unlocking "Full Bolt On" (FBO) power levels.

Why You Need This Upgrade

• Reduced Turbo Lag: By removing the bottleneck at the turbo exit, backpressure drops significantly, allowing the turbos to spool up faster and hit peak boost earlier.
• Massive Power Gains: On tuned vehicles, moving from stock "pancake" outlets to these high-flow pipes can yield 10-50 WHP depending on your boost levels.
• Heat Resistance: Constructed from T6-6061 Aluminum, these pipes won't expand, warp, or crack under the extreme heat cycles of the N54 engine bay like stock or silicone alternatives.
• Universal Turbo Fitment: The CAD-designed flanges ensure a leak-free seal on OEM Mitsubishi turbos as well as aftermarket upgrades like Pure, Vargas, and RB Turbos.

Installation & Fitment Notes

These are "Hot Side" outlets that connect the turbos to the intercooler. Installation Note: Installing outlets on an N54 is a tight job due to the location of the rear turbo and subframe. Access is limited, and patience is required. While these are designed to route around the steering column without modification, professional installation is recommended if you do not have access to a lift.

Stop suffocating your N54 with flattened stock pipes and flow the boost you paid for.
