• F11 Touring: Wide choices of sport stainless silencers, catback lines, downpipes, and decatalyzers.
• Custom duplex lines (left + right): High-resistance AISI 304/409 stainless steel options for aesthetic duplex looks.

These options fit various engine and chassis versions, ensuring proper compatibility and legal use.

Exhausts generally use:

• Predominantly stainless steel (AISI 304 or 409) for corrosion resistance and high-temperature durability.
• Approved components for road legality, such as homologated silencers and valves.
• Components include round 76mm outlets, welded mounting brackets, clamps, and rubber hangers.
• Optional use of race-spec catalytic converters with 100 CPSI ceramic monoliths.

This ensures long-lasting performance, minimal maintenance, and optimal sound quality tailored for each vehicle.

Yes, many exhaust systems and kits are designed for direct bolt-on installation or straightforward fitting using supplied clamps and brackets. They maintain compatibility with original BMW components such as catalytic converters and rear mufflers. Custom options also exist for tuning car performance and aesthetics while adhering to legal noise and emissions standards.

Sport and custom exhaust systems improve:

• Sound: delivering a distinctive, aggressive tone without excessive drone.
• Performance: optimizing exhaust flow can slightly increase horsepower and torque.
• Appearance: stylish stainless steel finish with options like duplex or round tailpipes.
• Durability: corrosion-resistant materials ensure longevity even in demanding conditions.

These benefits combine to provide a more engaging driving experience with premium quality engineering.

Key features include:
