Buying Guide for Motorhome Generator Exhaust Extension Kits
Choosing the right generator exhaust extension kit for your motorhome involves several key considerations to ensure safety, compatibility, durability, and noise control.
Compatibility
Check that the kit fits your specific generator model and exhaust pipe diameter. Many kits come with multiple adapters to fit a range of sizes, accommodating brands like Generac, Cummins, Honda, Yamaha, and more. Be sure to verify pipe sizes (commonly 1.25”, 1.4”, and 1.5”) to ensure a proper fit.
Material and Durability
Look for kits made from weather-resistant materials like high-quality PVC, aluminized steel, or galvanized metal that resist rust, corrosion, and oxidation. This ensures reliable performance in varying outdoor conditions and reduces maintenance or frequent replacements.
Noise Reduction Features
If noise is a concern, consider extension kits with silencers or mufflers and insulated mounting plates that reduce exhaust noise by up to 50% or more. Specially designed grilles and sound-absorbing materials help your generator run quietly, especially important in campgrounds or residential areas.
Installation Requirements
Some exhaust extensions require welding to the generator muffler, which may necessitate professional help. Others use clamps and self-drilling screws for easier installation. Universal kits often include hardware to modify fit as needed.
Safety Considerations
Proper ventilation extends exhaust fumes away from the RV living space, preventing exposure to harmful carbon monoxide. Look for insulated through-wall mounting plates and secure adapters that minimize leakage and maintain a healthy cabin environment.
Length and Flexibility
Extensions vary in length, affecting how far fumes are diverted. Make sure the hose or pipe length fits your motorhome layout, allowing exhaust to vent safely above roof level if possible. Flexible hoses can simplify maneuvering in tight spaces.
By evaluating these factors, you can select a motorhome generator exhaust extension kit that best suits your safety, comfort, and durability needs on the road.
