DIY Muffler
« on: April 06, 2019, 05:05:01 PM »
My children gave me a welder for Christmas. I thought it might be about time to learn how to use it. How about a DIY muffler project. I'd give it about an 80% chance of ending up in the scrap heap, but it will be fun and I'll learn a lot.

It's always good to have a project-now get rid of that ugly muffler clamp and pickup a T bolt clamp it'll look much better
It's not a big motorcycle just a groovy little motorbike

An educated guess....pretty light and pretty loud :001:

It's not as light as you might think. It's all made of steel and not particularly thin walled. I still have to put some kind of baffle in and then I'll get out the scale a find out.

With the can empty is doesn't sound very nice. Loud and tinny. It sounds better with just the mid pipe.

About done. When I started I thought I would learn a lot about welding and then throw it in the scrap. Time will tell if I keep it on long term but it seems to work pretty good and it sounds a little angry but not obnoxiously loud. 5.6 lbs less than stock.

Much longer than it should have  :157: I spent a lot of time filling holes that I burnt into everything (weld, grind, fix fill with screw heads, weld grind repeat). By the end I was doing much better so it got faster. I did not keep track of time and was often doing other things in the garage at the same time. Someone who knows how to weld could do it in an evening I expect.
