I did a quick search but didn't find anything here, but did find a few sites on the internet. I bought a pre-owned 3500W Craftsman generator off craigslist for $225. It is loud. And heavy. The heavy part I can deal with 'cause I'm young

The loud part annoys me, so based on what I've read elswhere on the internet, I'm going to quiet it. Here's the plan: yesterday I went to AutoZone and bought the cheapest car muffler I could find ($19.99) and some of the flexible exhaust pipe and two couplers. I will weld one coupler directly to the existing muffler on the generator. Once that is done everything else will just slide on. I will take photos and such of my progress and post them here. Once complete I will make a short video of a before and after to give everyone an idea of the sound reduction. I don't have a decible meter but I may invest in one to make this scientific and all

Stay tuned.
