BMW G80/G81 M3 Upgraded Aluminum Turbo Chargepipe Set – Reinforced Full Metal Design for Improved Reliability & Turbo Response | Fits G80 Sedan & G81 Touring with S58 Engine (2021–Present)

Replace the Weakest Link Before It Fails

The factory plastic chargepipes on the S58 engine are known to crack, split, or completely burst under high boost pressure — especially on tuned or aggressively driven G8X models. Heat, pressure, and vibration eventually fatigue the thin composite material, leading to boost leaks, check engine lights, and loss of power.

The BAVMODS® Upgraded Aluminum Chargepipe Set permanently solves that problem.

CNC-bent from high-strength aluminum and finished in a durable matte black powder coat, these pipes are designed to outperform and outlast your factory setup while maintaining a clean OEM+ aesthetic.

Engineered for the S58 Powerhouse

The G80/G81’s twin-turbo S58 inline-six generates massive boost pressure — even more so when tuned. This dual-pipe system is precision-built to handle those extremes without compromise.

• Dual Chargepipe Configuration: Replaces both front and rear turbo outlet pipes for full boost integrity across the twin-turbo system.
• Full Metal Construction: Crafted from aircraft-grade aluminum that will never crack or warp under load.
• Improved Boost Reliability: High-tolerance CNC flanges and reinforced couplers ensure a 100% airtight seal — no leaks, no limp mode.
• Enhanced Throttle Response: Smooth internal surfaces maximize airflow velocity, reducing lag and improving turbo spool characteristics.
• High-Temperature Resistance: Withstands extreme under-hood temps from track or spirited driving without fatigue or discoloration.
• OEM+ Fitment: Designed to integrate seamlessly with factory sensors and mounting points for a clean, bolt-on install.

Complete Plug-and-Play Installation Kit

Everything you need for a professional-grade installation is included — no trips to the hardware store mid-install.

Includes:

• Premium 4-ply silicone couplers
• Stainless steel T-bolt clamps
• Push clips, O-rings, and seals
• Pre-welded fittings and hardware
• Pressure-tested assembly for guaranteed reliability

This is a true bolt-on upgrade — designed to fit like OEM but perform far beyond it.

Why Aluminum Over Plastic?

BMW’s stock composite chargepipes were engineered for comfort and emissions compliance — not sustained high-boost performance. Over time, the plastic expands and contracts from heat cycles, eventually cracking at the throttle body or separating under pressure.

Once that happens, you’ll instantly lose boost and trigger a “Charge Pressure Control” or “Boost Leak” fault.

The BAVMODS® aluminum chargepipe set eliminates that failure point entirely.

Built to endure tuned boost levels, high heat, and long-term stress, this upgrade is the definitive solution for anyone running a tune, hybrid turbos, or simply wanting peace of mind.

Performance You Can Trust

This isn’t just a cosmetic upgrade — it’s a critical reliability mod for any G80 or G81.

Whether you’re running a factory tune or a full Stage 2+ setup, your turbo system depends on boost stability.

The BAVMODS® Upgraded Chargepipe Set ensures your S58 engine delivers consistent performance pull after pull — the same power on the 100th run as on the first.

Your S58 deserves confidence, not compromise.
