Valvetronic Designs Valved Sport Exhaust System for BMW M3 / M4 (G8X) 2020-2026

Unlock the full, rich character of the S58 engine with the Valvetronic Designs Exhaust System for the BMW G8X platform. This modular solution begins with a transformative 3.5-inch equal-length mid-pipe, engineered to eliminate factory harshness and deliver a smoother, higher-pitched, and more engaging tone. For complete control, add the optional valved axle-back to switch between a refined daily-driver experience and an aggressive, motorsport-inspired roar. Crafted from premium T304 stainless steel or ultra-lightweight Grade 5 titanium, it offers significant performance gains, seamless OEM integration, and a 100% reversible installation.

Key Benefits

  • Transforms the S58 Soundtrack: The equal-length 3.5-inch mid-pipe balances exhaust pulses for a crisper, more refined tone with reduced drone, whether using stock or aftermarket downpipes.

  • Complete Sound Control (Optional Axle-Back): The valved axle-back features a quad-chamber muffler and electronic valves, allowing instant switching between a quiet, civilized mode and a raw, aggressive exhaust note.

  • Significant Weight Reduction: Choose your performance profile:

    • Grade 5 Titanium: Save up to 57.8 lbs for maximum agility.

    • T304 Stainless Steel: Save 24.7 lbs.

  • Modular & Future-Proof Design: Install the mid-pipe alone for an immediate upgrade, or complete the system with the axle-back. It's engineered to work seamlessly and is guaranteed not to trigger a check engine light (CEL).

  • Premium OEM+ Integration: Features precision TIG welding, mandrel-bent tubing, and includes all necessary hardware. Valve operation can be via the included remote or integrated with factory drive modes.

Detailed Features & Specifications

  • Core Design: Single 3.5-inch equal-length mid-pipe; 2.75-inch valved axle-back (optional).

  • Material Options: T304 Stainless Steel or Grade 5 Titanium.

  • Valve Control: Electronic valves with included remote controller; optional OEM integration available.

  • Weight Savings vs. OEM Exhaust:

    • Full Titanium System: Up to 57.8 lbs lighter.

    • Full Stainless System: 24.7 lbs lighter.

  • Fitment: 2020+ BMW G80 M3, G82 M4 Coupe, and G83 M4 Convertible.

  • Included Components: Mid-pipe assembly with cross brace, all necessary clamps and hardware. Axle-back system (if selected) includes valves, controller, and tips.

Important Installation & Compatibility Notes

  • Cutting Guide: When installing only a mid-pipe or axle-back, the OEM pipe must be cut at the second dimple for proper fitment.

  • Version Compatibility: V1/V2 components are not compatible with this latest V3 system. The V3 mid-pipe includes designed clearances at connections.

  • Reversible: Designed as a 100% bolt-on system that can be returned to stock at any time.

  • Recommended Pairing: For the most refined tone with aftermarket downpipes, high-flow catalytic converters are recommended
