Generator Exhaust Extension Silencer Kit with Insulated Through-Wall Mounting Plate - Includes 3 Adapters - Fits All portable Generators

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.

I have a duel fuel generator in my shed in the yard. My power goes out to the shed from the house using a #6 wire. ( I previously had a pool filter which was supplied by power from the shed) I'm using the only connection to the house to run power from the generator back to the house. The issue was CO build up in the shed which would shut down the generator. Alas!!!! Along comes Zombie Box with a external exhaust tube to connect and run exhaust out of the shed; brilliant! (wish I had thought of it!) I order the muffler kit, which arrived as advertised, and hooked it up. (See photos) The muffler doesn't get too hot on the outside so it's really safe. I was worried because I have a grand daughter who could come in contact if she was over here and it was running. Also worried about CO but the exhaust tube works great. I added muffler sealer paste and two layers of Tiger Tape muffler sealer. I close the shed, run the unit and no CO build up. This is great for keeping my generator out of the weather and protected from the elements. No more moving it around!

I installed this to my Firman T07571 I bought from Costco and measured a significant sound level reduction. Without this muffler I measured a sound level of 108db next to the generator. After installing this muffler, I measured the sound level all around the generator and measured a sound level of 89db. I hear most of the noise is from the mechanical moving parts of the generator. I installed this to my shed and when I closed the door and measured the sound 20 feet away, I measured a sound level of 68 db.This kit also fits the Firman T07571 very well. I only wish this is available in stainless version.

Bought this to allow the exhaust to exit my generator shack due to heat and lack of fresh air . 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.

It’s advertised as an exhaust silencer. It is not. In fact you can look straight thru the “silencer”. No baffles, no silencing material, it actually increased the decibels of my exhaust by acting as an echo chamber.The “insulated thru wall adapter” is no more than a sheet metal plate with a 3” dryer duct fitting tack welded in. There is nothing insulating about it. The silencer does not fit tight in the wall adapter causing the silencer to vibrate…metal on metal, adding more noise.The idea is great, this isn’t the product for improving noise.What this would work for is if you have a shed, away from your home and you wanted to extend the generator exhaust thru the wall.

Easy to install to my shed, makes my generator so much quieter.. I had to make modifications to the outlet flange to fit my generator which is a westinghouse but I made it work perfectly and that was my own fault for not checking the fitment lol The main thing is I got it to work as intended with a few mods... Works great.

After upgrading my generator to one with more wattage, I had to do some modifications to my generator box. This product fit the bill nicely. The exhaust flange adaptor fit my Champion generator with no modifications needed. I purchased an exhaust manifold gasket to make a better seal between the generators exhaust outlet and the adaptor flange. I also took the muffler to a shop to have a 90 degree elbow welded onto it to direct the exhaust flow toward the ground. Nice quality product.

My husband asked for this for his boat. Very happy.
