Akrapovic Slip-On Line Titanium Exhaust System for 2021-2026 BMW M3 (G80) / M4 (G82/G83) - S-BM/TI/33H

Fits 2021-2025 BMW M3 (G80/G81) and 2021-2026 BMW M4 (G82/G83) models, including Competition, xDrive, CS, and CSL variants.

Constructed from high-grade lightweight titanium, the Akrapovic Slip-On Line exhaust system offers a sophisticated weight reduction of 35% over the factory setup. This precision-engineered system features a pair of titanium collectors cast in the Akrapovic in-house foundry, ensuring optimal gas flow. The sound character is meticulously tuned to provide a rich, refined tone during cruising that transforms into a deep, aggressive sporty note under load. No ECU remapping is required for this configuration, making it a direct-fit performance upgrade for both OPF and non-OPF vehicles.

• Performance Gains: +10.9 hp (8.0 kW) at 6,000 rpm and +13.9 Nm of torque at 5,000 rpm (tested against M4 Competition).
• Premium Construction: Full high-grade titanium mufflers and link pipes for durability and heat management.
• Weight Savings: 35% lighter than the standard OEM exhaust system.
• Akrapovic Control Kit: Included to manage the exhaust valves for a complete acoustic experience.
• Mandatory Components: Requires a carbon-fibre tailpipe set (TP-CT/69, TP-CT/68, or TP-CT/73/CF) sold separately.
• Manufacturer Part Number: S-BM/TI/33H

Note: While the system fits all listed models, the ECE certificate is specifically valid for cars equipped with an OPF filter and is not valid for CSL models. For closed-circuit usage, optional link pipes and downpipes are available to further enhance flow and sound.
