Don’t skimp out on quality parts, even if it’s a silencer.
Old vs New
The shiney one is much more quiet, but restrictive as hell. And it’s all due to this design
It forces the exhaust flow around the blockage and through the holes on the inner cylinder. While the newer one has only a center opening on the inner cylinder. It’s a tad bit louder but not by much, and definitely not as restrictive.
Notice you can still hear the music! Definitely a good silencer if you want to just “cruise” and not attract attention. Peace for now.
