Exhaust BMW 1 Series

Exhaust systems for BMW 1 Series include original parts, stainless steel sport silencers, complete cat-back lines, and custom exhausts. They are designed for petrol and diesel engine options to enhance sound, performance, and appearance.

Compatible models cover mainly:

• E87 (2004-2012) including 116i, 118i, 120i, 130i petrol engines and 118d, 120d, 123d, 114d diesel engines
• E82 M-Sport (2008-2012) diesel cat-back systems
• F20 (2011-2015) diesel with stainless steel intermediate silencers and duplex pipes

Specific references and technical specifications are tailored per engine and model year.

Stainless steel (inox) is the primary material used due to its resistance to corrosion and durability. It ensures lasting performance and a sporty sound without rusting. Some high-end systems also utilize lightweight titanium, but stainless steel remains dominant for aftermarket and OEM quality exhaust systems.

• Stainless steel: Durable, corrosion-resistant, enhances sound
• Titanium: Premium option, heat-resistant and lighter (less common)
• Complete cat-back lines replace the exhaust from the catalytic converter rearwards
• Custom systems can include race catalytic converters for enhanced flow

Exhaust tips can be single or dual, available in various sizes to suit aesthetic preferences.

Several reputable manufacturers produce exhaust components for the BMW 1 Series, including:

• RC Racing: Stainless steel sport silencers and group N systems particularly for E87 models
• Milltek: Complete cat-back stainless steel lines especially for E82 diesel variants
• Fox Exhausts: Rear silencers targeted at specific petrol engines
• Ragazzon: Duplex stainless steel systems for F20 models
• Supersprint: Stainless steel sport silencers for E87

These manufacturers focus on high-quality materials, durability, and performance enhancements.

Aftermarket exhaust systems can improve exhaust flow, reduce backpressure, and enhance engine sound. This leads to better engine efficiency, a sportier exhaust note, and sometimes a slight increase in horsepower. Specifically, stainless steel cat-back lines and optimized silencers contribute to this performance and aesthetic upgrade while maintaining durability.

Key considerations include:

• Vehicle model and engine type (petrol or diesel) for compatibility
• Material quality, with stainless steel recommended for longevity
• Exhaust design: cat-back systems for complete rear replacements or sport silencers for specific upgrades
• Sound preferences: from subtle to more aggressive exhaust notes
• Legal compliance and emissions regulations, including catalytic converter specifications

Always verify installation compatibility and consult professional technical support if needed.

High-quality exhaust products from reputable manufacturers typically come with warranty coverage, often up to 3 years or a mileage limit (e.g., 100,000 km), covering defects in materials and workmanship. Policies vary by supplier, but commonly include a free return option within 30 days for unused products in original packaging, subject to terms.

• Warranty usually requires professional installation and proper maintenance
• Products must be unused and returned in original condition for returns
• Check supplier-specific warranty conditions and service support

It's important to retain purchase documentation and follow installation instructions for warranty validity.

Technical support is generally available via email or phone from authorized exhaust system providers. They can offer installation manuals, compatibility confirmation using vehicle identification numbers (VIN), and advice on sensor positioning. For specific measurements and technical data, always refer to the manufacturer or supplier documentation.

• Confirm product compatibility with your BMW 1 Series model and engine
• Request detailed installation guides and support if unsure
• Ensure replacement parts meet legal emissions standards

Professional installation by qualified garages is recommended for optimal performance and warranty compliance.
