Vanagon – home made muffler update
Posted by albell in vanagon, vanagon mods on August 20, 2021
I made a muffler eight years ago. Here’s a link to all the blog posts about construction then.
Since then I’ve added a working cat, and new exhaust pipes. But I’ve also hit the muffler a few times on rocks and snow banks. Hit it enough that I cracked the weld at the tail pipe end of the muffler.
So when the engine was out recently I cut that end off and re-welded. Gave me a chance to look inside and see how the stainless steel swarf I used as muffler packing was doing. Was a little sooty, not much, a little discoloured by heat, but overall surprisingly good. Don’t know why I was expecting any different.
Gave the muffler a bit of a buff to take off dirt and shine it up a little. Also made new hangers. Same style as before but stainless pins to hold the band clamps instead of aluminum. It’s 3/8” aluminum, 1/2” diameter on the pressed in pins. Oh and new band clamps.
Sounds more or less the same as before. Yes, louder than stock.
