Automotive exhaust accessory, the MaxEarn Exhaust Muffler, aims to reduce noise from diesel parking heaters and small generators. Quieter operation makes late-night heater use less intrusive for van owners and caravan enthusiasts and allows longer external exhaust routing. Is the muffler durable and straightforward enough for workshop or DIY fitting?
⚡ At a Glance
- • Noise Reduction: Porous S-shaped internal design, around 20% higher noise reduction than older designs (manufacturer claim)
- • Best for: Owners of vehicles or equipment with diesel parking heaters who want quieter external exhaust routing
- • Not ideal for: Applications requiring larger diameter exhausts or manufacturer-specific certified parts
Porous S-shaped internal geometry reduces airflow pressure and increases acoustic resistance. Aluminium alloy construction adds heat and corrosion resistance while included clips and screws simplify replacement on compatible 24mm outlets.
Quieter heater operation - with porous S-shaped internal design
Porous lining reduces airflow pressure while the S-shaped pipe increases acoustic resistance points and disrupts sound wave propagation, lowering overall noise. The manufacturer claims roughly a 20% improvement versus older muffler designs.
Noticeably reduced heater and generator noise during operation, making late-night use less disruptive. Practical for vans, caravans and vehicles that need longer external exhaust routing.
Durable under heat and corrosion - with aluminium alloy construction
Aluminium alloy offers heat resistance, corrosion protection and wear resistance compared with lower-grade metals. The material choice supports prolonged exposure to hot exhaust gases common in diesel heater systems.
Longer service life in harsh under-bonnet or external mounting positions, reducing the need for frequent replacements. Suitable for regular use in automotive and generator exhaust applications.
Quick and secure replacement - thanks to included stainless clips and screws
Two stainless steel clips and fastening screws allow clamp-style connections to standard 24mm exhaust outlets, avoiding complex welding or bespoke fittings. The small hardware set suits straightforward snap-and-tighten installation.
Simple DIY swap-out for a worn or noisy silencer, achievable in a short garage session. Secure mounting reduces the risk of leaks and movement during operation.
