Not really eco related, but I finally "fixed" my muffler problem.
Last April my muffler, um, fell off. A casualty of rust. It really wasn't too loud, far quieter than your typical fart can, so I didn't worry about it.
Well, I need to get through emissions testing, so I figured I needed to address it. So, I welded a little pipe and a turndown back on it. With the turndown, it's a little quieter yet, so it will probably stay this way.
Oh, I just noticed you can see my fancy, home-made ramps too.
