FMF Q4 exhaust on DRZ400SM Uncorked vs Quiet Core vs Spark Arrestor

Quick video to show sound difference between running the quiet core insert, spark arrestor only, and also uncorked.

Running with the mesh style spark arrestor there is only a slight reduction in sound compared to no insert. Revving up and WOT sounds very much like running uncorked.

With the quiet core insert, in person, it makes the exhaust a lot quieter, especially when revving or WOT.
