Upgrade the restrictive factory turbo outlet plumbing on your BMW N54 with the XS-POWER 2-inch High-Flow Aluminum Turbo Outlet Pipe Kit. Designed for compatible left-hand-drive BMW 135i, 535i, 535xi, Z4 and 1 Series M Coupe applications, this performance outlet system provides a larger and smoother airflow path between the twin turbochargers and intercooler.

The original N54 outlet assembly can become a restriction as boost pressure, turbocharger airflow and engine power are increased. The factory-style plastic and narrow tubing may also become brittle with age, heat and repeated boost cycles.

This upgraded aluminum outlet kit replaces the restrictive factory-style piping with durable 2-inch aluminum tubing, helping the turbochargers move compressed air more efficiently toward the intercooler. The improved flow path can sharpen throttle response, reduce pressure loss and help decrease perceived turbo lag when used with the proper supporting modifications and ECU calibration.

The kit is designed to work with turbochargers and intercoolers that retain compatible OEM-style outlet connections. It is an excellent upgrade for stock-turbo vehicles, upgraded-turbo builds, daily drivers, street-performance cars and track-oriented BMW N54 projects.

Finished in black for a clean engine-bay appearance, the XS-POWER outlet kit combines high-flow performance, durable aluminum construction and application-specific routing for compatible E82, E88, E89 and E60 chassis vehicles.

The BMW N54 uses two turbochargers that send compressed air through outlet pipes before the airflow reaches the intercooler. As power and boost pressure increase, restrictive factory piping can create unnecessary turbulence and pressure loss.

A larger aluminum outlet system gives the turbochargers a more efficient path for moving compressed air. This can help the engine respond more quickly and maintain airflow more effectively throughout the RPM range.

• Improves airflow from both turbochargers
• Reduces restrictions in the charge-air system
• Helps support increased boost and airflow
• Improves durability compared with aging factory plastic components
• Supports upgraded intercoolers and performance turbochargers
• Provides a stronger foundation for tuned N54 builds

• Higher-flow outlet path between the twin turbos and intercooler
• Improved throttle response under boost
• Reduced airflow restriction compared with factory-style piping
• Potential reduction in turbo response delay
• Improved charge-air system durability
• Supports stock, hybrid and upgraded N54 turbocharger systems
• Ideal for street, drag, road-course and daily-driven performance applications
• Clean black finish for an upgraded engine-bay appearance

Final performance results depend on turbocharger size, boost level, intercooler efficiency, intake system, exhaust system, ECU calibration, fuel quality and overall engine condition.

The listing photographs show the actual style and configuration of the components included. Minor hardware or finish details may vary between production batches without affecting intended fitment or performance.

This system is engineered as an application-specific performance upgrade. Installation is easier than fabricating a custom outlet system, but access around the N54 twin turbochargers can be limited.

• Allow the engine and turbochargers to cool completely before installation.
• Remove the original outlet piping and inspect all connection points.
• Test-fit each aluminum section before fully tightening clamps.
• Confirm adequate clearance from steering, suspension, exhaust and engine components.
• Position all couplers fully over the pipe bead before tightening.
• Tighten clamps evenly without crushing or deforming the aluminum tubing.
• Pressure-test the charge-air system after installation.
• Recheck all clamps after the first complete heat cycle.

Professional installation is recommended. Installation time may vary depending on vehicle condition, existing modifications, turbocharger configuration and installer experience.

XS-POWER has supplied performance turbocharger, exhaust, intercooler and charge-air components to automotive enthusiasts around the world for decades.
