CUMMINS NW Cummins Onan Tail Pipe/Exhaust Kit
This kit is specifically designed for Cummins HGJAB RV generator sets and includes a tailpipe, clamp, and hanger. It comes with a built-in USDA Forest Service approved spark arrester muffler, ensuring compliance with safety regulations. Installing this tailpipe is necessary during generator setup to properly direct exhaust gases and protect surrounding areas from sparks. Its compatibility with Cummins Onan models makes it a reliable choice for RV owners seeking durability and regulatory adherence.
Camco Gen-Turi RV Generator Exhaust Venting System
The Camco Gen-Turi system improves RV air quality by directing generator exhaust above the roofline, preventing harmful fumes from entering the living space. Its rubberized straps reduce vibration transfer and exhaust noise, contributing to a quieter camping environment. The kit includes adapter fittings that accommodate exhaust pipes ranging from 1 to 2 inches in diameter, ensuring wide compatibility with most RV generators and trailers. Its ease of installation and disconnection makes it a practical, user-friendly option.
RV Generator Muffler Hanger Tail Pipe Exhaust Bracket – Black
Designed for Onan Cummins generators, this exhaust hanger features a powder-coated black finish that enhances resistance to weather conditions. The bracket measures 8.5 inches from top mounting hole center to pipe location, fitting exhaust pipes with outer diameters between 1.25 and 1.75 inches. It’s primarily intended to provide strong, stable support for the exhaust pipe, reducing stress on mounting points and mitigating movement during generator operation.
BSTGEKELY 44461 RV Generator Exhaust Extension Kit
This extension kit offers adaptability with three included adapters sized 1.5″, 1.4″, and 1.25″, making it compatible with brands such as Generac, Cummins, Honda, and Yamaha. Constructed from oxidation and abrasion-resistant PVC, the exhaust extension withstands various weather conditions. Its purpose is to extend the exhaust pipe length, directing gases farther away and mixing them with fresh air to minimize fumes around the campsite, enhancing user comfort during generator operation.
Zombiebox Generator Exhaust Extension Silencer Kit
The Zombiebox silencer kit fits most portable generators, offering a complete solution including a muffler silencer, flexible hose, three types of universal muffler adapters, clamps, and a through-wall mounting plate. Made from industrial-grade aluminized steel and powder-coated materials, it resists corrosion and rust. The mounting process allows flexibility as adapter holes may need modification, supported by self-drilling screws. This kit not only extends but also significantly reduces exhaust noise, improving overall generator usability.
Buying Guide for Selecting the Best Exhaust Pipe for Your Generator
When selecting an exhaust pipe for a generator, several important factors should guide your decision to ensure compatibility, safety, and performance:
Compatibility
Check the generator model and exhaust pipe diameter. Products like adapter kits or universal exhaust extensions offer flexibility, fitting a broad range of generators from RV models to portable units. Tailpipe kits designed for specific brands, such as Cummins or Onan, provide a better fit without modification.
Materials and Durability
Opt for exhaust pipes made of heat-resistant and corrosion-proof materials like stainless steel, aluminized steel, or high-quality PVC. Powder-coated parts add extra weather protection. Durability is crucial as exhaust systems are exposed to heat, moisture, and outdoor elements.
Noise Reduction
Some exhaust pipes come with mufflers or silencers to minimize generator noise. This is especially valuable in camping or residential settings where quiet operation is appreciated. Accessories like flexible hoses and vibration-damping mounts help reduce noise and wear.
Installation and Maintenance
Choose exhaust extensions or kits that are easy to install and maintain. Systems with clamps, adapters, and straightforward mounting hardware reduce setup time. Also consider kits that allow for easy disconnection or replacement without specialized tools.
Safety Features
Look for exhaust pipes featuring spark arresters or USDA-approved mufflers to prevent fire hazards, especially when using generators near combustible materials such as dry grass or wood. Ensuring exhaust gases are vented properly away from living areas protects occupants from harmful fumes.
Size and Length Considerations
The pipe’s length affects where the exhaust gases are released. Longer extensions direct fumes further away, improving air quality around the generator. However, excessively long pipes may reduce exhaust flow efficiency or complicate installation, so balance length with practicality.
By evaluating these perspectives—compatibility, durability, noise control, ease of installation, safety, and size—you can choose the best exhaust pipe tailored to your generator’s needs and environment.
