MMR High-Flow N55 Turbo Outlet Charge Pipe Boost/Discharge Pipe - BMW F-Series M135i M235i 335i 435i M2 (F20 F21 F22 F23 F30 F31 F32 F33 F87) | Alloy Compressor Outlet Hot-Side Intercooler Pipe | OE-Style Direct Replacement Upgrade

Stronger, smoother flow from your N55 hot side

Replace the fragile plastic outlet on your turbocharged BMW with a robust metal compressor discharge tube that is built to handle increased boost pressure. This high-flow charge air hard pipe gives your F-series N55 a tougher, more reliable hot-side path to the intercooler, helping reduce pressure loss and sharpen pedal response on mapped and stock cars alike. A smart upgrade for spirited road use, fast road builds and track sessions.

Why enthusiasts choose this turbo discharge tube

• Alloy construction resists cracking and ballooning under load compared to the factory moulded part
• Smooth internal bore for less turbulence and improved charge air velocity
• CNC-turned ends and precision connections for an airtight seal with OE couplers
• Textured black powder coat with discreet laser-etched branding for an OEM-plus look
• Bolt-in fitment using standard hardware, no cutting required
• Confidence for Stage 1 and Stage 2 tunes as well as completely standard vehicles

We have installed this outlet tube on our own development cars and many customer vehicles. Owners consistently report quicker boost build, cleaner throttle pickup and dependable performance pull after pull.
