Generator wouldn't run closed up. After the exhaust Kit and a fan operated vent system. It runs well now. Kit is well made and includes all parts necessary for most instalations. Be aware that it is Not Quiet! Sounds like glass pack. Your neighbors probably won't like it, but you might smile. Review: Will give ability to run in the garage. - Item is great. Flange needed modified for 5/16" bolts. Some grinding may be needed for clearance. We have a Generac generator, which is on the list. Have not gotten it installed yet, so I don't know the sound level yet. ## Features - THE ORIGINAL: All others are knockoff of the Zombiebox universal generator exhaust extension silencer kit. 3 Universal adapters allow for connection to any generator, for safe venting of exhaust fumes from a DIY enclosure or space, like a garage or shed. Fits MOST portable generator makes and models! Some modification of the adapter may be required. 3 adapter styles included for you to find the perfect fit: including slip-on, bolt on and collector style. With gaskets. - MULTIPLE WAYS TO INSTALL: The exhaust adapter bolts onto the generator's stock muffler outlet. Self-drilling screws are included for generator mufflers that don’t have holes or holes that don’t line up to mount the generator exhaust adapter, otherwise you can use generator’s original bolts. 5 inch hole recommended for wall mount bracket. NOTE: mounting holes might not line up to the muffler you have - NO WORRIES - use the supplied self drilling screws to attach it directly to the muffler or shroud. - RUST FREE INDUSTRIAL MATERIALS: Made from industrial-grade aluminized steel alloy, galvanized sheet metal, and powder-coated parts to prevent corrosion and rust. Includes: 3 styles of universal muffler adapters, 2 clamps, 1 flexible hose, 1 muffler silencer, 1 wall mounting plate. - IMPROVED EFFICIENCY & AIRFLOW: Engineered for lower noise emissions and maximum engine efficiency. No engine back pressure allows for safe venting of exhaust fumes from an enclosure, shed, or barrier. Prevents carbon monoxide buildup and shutoff problems in DIY enclosures. This kit will change the tone of the stock exhaust noise. For more noise reduction, purchase a ZHut Zombiebox Acoustic barrier. - THE ORIGINAL EXHAUST EXTENSION: Invented and perfected in the USA, Zombiebox is the first and best generator exhaust extension for portable generators. Minimal thermal transfer to wall or enclosure. (*Only when enclosed in a ZombieBox, shed, or outbuilding will it make the exhaust noise quieter). DO NOT remove your generator's muffler system; ADD this system to it! NO FREE RETURNS. - CO SENSOR SAFE - FITS MOST GENERATORS: Fits Westinghouse, EcoFlow, Pulsar, Ryobi, Firman, Honda, Duromax, WGen, Genmax, Predator, NorthStar, PowerHorse, Champion, Generac, & More. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CJDH2YRR | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #58,129 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #846 in Outdoor Generators & Portable Power | | Brand | Zombiebox | | Brand Name | Zombiebox | | Compatible with Vehicle Type | All | | Customer Reviews | 4.2 out of 5 stars 282 Reviews | | Global Trade Identification Number | 00860008101440 | | Included Components | Premium Zombiebox Glass Pack Muffler, 2ft.

Generator wouldn't run closed up. After the exhaust Kit and a fan operated vent system. It runs well now. Kit is well made and includes all parts necessary for most instalations. Be aware that it is Not Quiet! Sounds like glass pack. Your neighbors probably won't like it, but you might smile. ### ⭐⭐⭐⭐ Will give ability to run in the garage. *by P***S on August 2, 2025* Item is great. Flange needed modified for 5/16" bolts. Some grinding may be needed for clearance. We have a Generac generator, which is on the list. Have not gotten it installed yet, so I don't know the sound level yet. ### ⭐⭐⭐⭐⭐ Decibels Noticeably Lower, but still Very Loud *by K***R on March 29, 2025* Super easy to install and custom fit to my generator setup. I did end up "corking" the exhaust port while not in use. I was worried rain might get in. In my head I thought it would reduce the noise more, but generators are so loud muffled or not. With this you will only bother your next door neighbor. Not the whole block. ## Frequently Bought Together - Zombiebox Generator Exhaust Extension Silencer Kit with Insulated Through-Wall Mounting Plate - Includes 3 Adapters - Fits All portable Generators - SunplusTrade 2" x 50' Black Exhaust Heat Wrap Roll for Motorcycle Fiberglass Heat Shield Tape with Stainless Ties - HG Power Upgraded 10 Inch Shutter Exhaust Fan, 647CFM Low Noise Shed Exhaust Fan with Mesh Screen for Basement, Gable, Chicken Coop Ventilation Use, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/564232966-zombiebox-portable-generator-exhaust-extension-silencer-kit-exhaust-extension-system](https://www.desertcart.sn/products/564232966-zombiebox-portable-generator-exhaust-extension-silencer-kit-exhaust-extension-system) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-24*
