I fiddled around with different end caps instead of the spark arrestor. As soon as you put anything in its place you loose the deep thumper sound.
Altering the stock muffler really doesn’t change the one thing I was going for- weight loss. That stocker is heavy.
The Delkevik isn’t loud in my opinion, looses a lot of weight and looks better. All for a reasonable price. It also gives me a deeper tone at low Rpms. I leave the baffle in.
It would be interesting to alter/drill holes to see how it changes the sound. I am keeping my oem in case I want to switch back for some reason.
If this was local to me I would buy it to experiment on.
