Zombiebox Portable Generator Exhaust Extension Silencer Kit | Exhaust Extension System | 3 Adapters Included | Reduced Noise | High Efficiency | Fits ALL Portable & Backup Generators | U.S. Company

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.

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!

Item preformed as advertised. The holes on adapter did not line up, instead of drilling out I cut the original off muffler then attached flex extension with clamps provided and attached new muffler. Removing original muffler was the challenge. Would recommend to family and friends.

This exhaust extension silencer is really, really nice. I had to drill out the holes a little bit on the exhaust adapter but other than that it was super easy to install. Now it keeps my generator out of the elements and it has a real nice purrrr to it. It does exactly what I needed it to do. Thank you Zombie Box.

Bought this for a Westinghouse 10500TFc Generator. After removing the spark arrestor, The exhaust adapter worked ok but you do need some high temp RTV gasket maker, bought some with a temp rating of 750 degrees and so far it fixed the small exhaust leak between the adapter and the muffler. The muffler, suppressor or baffle or what ever it is called that comes with the zombie box does not help hardly at all with reducing the sound and the flexible metal hose that comes with it is a bit short and does limit options for where the Generator can be placed, if this flexible metal hose was another 2 feet longer or even two of them with an adapter to connect them together would be good. The Westinghouse 10500TFc Generator is loud and was hoping the zombie box would have make it a bit quieter. The Generator is in a shed made from 1/2 - -3/4 inch plywood and is insulated for sound (Walls, and ceiling) and still it is loud. Overall it works well as an exhaust diverter but as something that keeps the noise down, not so much.

Easy install snug fit.

No instructions. Very very very loud. Generator began to smoke almost immediately. Put the old one back on, no problems. I would not recommend this is you are looking for something to keep it quieter.

Good quality and prompt delivery

Product was perfect for what I needed. It extended the exhaust from our back-up generator and reduced overall noise level. Great product, easy to install, instructions were adequate.

Perfect solution for my generator exhausting through wall. I'd give it 5 stars but the thre tiny welds that hold the ring into place are very weak. One broke already and haven't used it a long time. Easy to fix, but that really isn't the point tho..

Amazing! Perfect fit with my Champion generator 8,000W. Easy to install and decrease the sound.

Left the spark arrester on as it made a better flush fit. Put my exhaust out through the floor of my shed and got another pc of extension from Canadian tire to place on the end and point out the shed bottom. Have fired it up a few times and it sounds good and looks like it will stay together.

Description says Universal, it is not. I have a Champion 9000 watts Dual Fuel generator with 7250/6525 running watts. The privided fittings do not fit. I contacted the seller and am waiting for his answer. Product seems good but is NOT universal. On the generator, I had to shave the exhauxt end about 3/16" using a grinder to make it even with the surface. Then ordered a exhaust gasket and sandwich it between the surface. Gasket model: BRIGGS & STRATTON #691893 available on Amazon. I also bought longer screws in case. Screwd are metric. Screws type: M5 20 mm long.
