Generator Exhaust Extension Silencer Kit with Insulated Through-Wall Mounting Plate 1 universal muffler adapters

Have not used yet. Would buy again

Well, I submitted a video that was rejected by amazon that addressed these shortcomings. I am a credentialed engineer (retired) and so I give my honest professional opinion of this kit in this updated (written) review.Firstly, RUFUS insists that the hole in the mounting plate is 5 inches when in fact it is 3~3 1/8 inches in diameter. It is shown as such above in one of the photos. If you ask RUFUS it insists that the mounting plate opening is 5 inches in diameter!Why is this an issue? Half of the installations in this country will be in a concrete block, cinder block, or brick wall and in those circumstances there's no need for a 5 inch hole because these materials, in this universe, don't burn.A thermal barrier of 2 inches spacing between the 3 inch mounting plate diameter and a concrete, cinder, or brick wall is completely unnecessary for that reason. They don't catch fire! This should be intuitively obvious.The adapter and the muffler, as shown in the above photos with dimensions, clearly show a disparity in dimension between the hose I.D. and the O.D. of the adapter and muffler. The stainless steel hose, given its hardness, cannot be cinched (mechanically) down over these adapters using the supplied clamps. Another reviewer commented on this fact and I have verified the same. The instructions don't address this issue and one other reviewer above surmised that the foil tape was to be used to make up the difference in I.D. and O.D.'s.The supplier, and I hesitate to say they're the manufacturer of these components, should address this issue. In my professional opinion, using foil tape with an adhesive side to make up the difference between the two is not what would be considered "good practice" and could be unsafe because as the glue on the tape melts, the spacing becomes less and the mechanical connection can slide off due to the melting glue.The muffler and the adapter ends should be swaged to a larger diameter to provide for a safe mechanical connection that isn't going to slide off the end as a result of melting adhesive on the tape. The hot adhesive will actually morph into a lubricant that will cause this disconnect.I made a distinction above between manufacturer and supplier. I don't believe (my speculation) that they're one in the same. I believe these parts are packaged as a kit by the supplier but are not manufactured by them (purchased parts), hence the lack of control over O.D.'s and I.D.s.So, for these reason, I do not recommend this product!

Quality construction with the pieces and parts you would need to connect to a portable generator. For me, however, I needed it to connect to the generator (Westinghouse) exhaust which had it's screws spaced at 2 inches. The adapter for this exhaust kit could only handle 1 3/4 inch spacing. If only this small adapter were engineered to handle a little larger range, I would have kept the kit. Unfortunately, I had to send it back.

Good fit ,quiet.

This bare bones kits come with sun standard hardware, pipe is so rigid that it makes impossibility short and adapter dosent fit without modification honestly given price and work and replacement parts I would been better off building my own
