Will a Car Muffler Make a Generator Quiet?

hey guys welcome back so today I brought home another generator this one is a power boss and basically just a rebranded Briggs you know storm responder type generator this one starts sounds great makes power can't find anything wrong with it really it does what it's supposed to do I think all it needs is project an oil change and maybe an air filter but there is something pretty interesting or different about this one and I thought I'd spend a little time testing it to see if it's really worth the effort to do something like this and as you can see someone put a car exhaust system on here and they attached it directly to the OEM system so it's kind of going through two mufflers so would be twice as quiet right well I'm not so sure about that so I do want to measure how loud this is I'm gonna get a decibel meter and we'll do a quick test the way it is now I'll put it back to how it should be and we'll do another test just to see you know what kind of a difference we're talking about okay so I've got this decibel meter app running over here and I'm about 25 feet away from that generator so I'm just going to start it up and see what we get and one thing to note this exhaust does have a hole in it so the readings gonna be probably a little high cuz I do hear a lot of noise coming out of there I'm gonna block it off with some wood just to get the exhaust to flow through as much as possible through that car muffler okay that was pretty loud I guess the big question is is a quieter than the stock exhaust so let's get that car muffler cut off and we will try it again okay so before I begin making sparks cutting off that muffler I do want to get the fuel tank off I have already disconnected the fuel line's yeah just got a root four bolts going around she left right out the only thing I'm not sure about is you know will this handle obstruct it coming out so let's remove those bolts and see how it goes okay so this side I can just on the screw and this whole assembly will come off I've already fed out these tabs which keep the bolts from spinning out so that one's actually loose anyway this sides not going to be an issue over here it's tack welded so I'm gonna cut those off and that should allow this side to come right out now I am gonna tie probably a rope or something just from here to here to help support it once I cut those tacks off so that I don't end up damaging something over here with the exhaust bolts up to the engine I decided to reverse my plan here I've got this tied up over here I'm gonna take those bolts out that go to the engine and just kind of let this dangle a bit and then attack those welds on the other side alright so I'm just going to use a dremel cutting wheel obviously I could use something bigger and do this quicker but I think I'll probably end up cutting too much of the frame so I'll have a little more control with this at least that's the theory like it never happened so the new muffler came in it actually looks a little bit worse than the old one well if the old ones didn't have a car exhaust on it but since it doesn't I'd say it looks quite a bit better so I'm just going to bolt that up and reinstall the fuel tank so that looks a lot better looks like a normal generator now a lot of these Briggs & Stratton setups have a standard muffler like this and I have one of these just hanging around on a shelf but the big consideration here is that you need a heat shield because this muffler is so low it can radiate heat into the stator back there so this has no heat shield and because the muffler is so high you don't need one the only heat shield you need is to protect the fuel tank because it's plastic but there's not going to be any heat radiating to that stator from the exhaust now one thing I don't think was considered when someone installed this is that that tailpipe there was exiting kind of over here and the stator has a fan in it it sucks cool air in on that end it exhausts it right here so potentially some of that hot exhaust air was circulating through the stator and may have shortened the life of that stator so if you're considering doing something like that keep that in mind you don't want hot air going into that stator so I got the meter set up again and I'm gonna start the generator to see how much louder it is with the stock exhaust and I do expect it to be louder I guess the question is how much louder okay so that was pretty conclusive the car muffler was quieter that came in at 70 decibels and this one was at 75 decibels so you know I knew this would be louder I just didn't know how much louder and to be honest both were pretty loud but you could tell this one definitely packed a bigger punch anyway is it worth doing would I do it probably not but if you're wondering if it'll work yes but just don't have unrealistic expectations as far as what its gonna do it's gonna be loud either way anyway I hope this video helps someone thanks for watching
