A dense sound with a core

Impression
The whoosh of the intake sound is more audible than before, and the muffler sound seems to have a more solid, dense sound with a core.
The price may seem high, but if you reverse the installation direction, the recommended replacement interval is 20,000 km, so it doesn't seem particularly expensive.
