低音量インサートキット 99db YZFR1 TRC マフラー

I was worried about noise complaints at my local track, but this insert kit dropped the sound just enough to pass their 99db limit. The machining on the baffle is clean and it slid right into my TRC muffler without any fuss. For the price of an optional kit, it’s a solid fix for stricter sound restr

The install was simple and the machining is clean, so it slid right into the muffler without any fuss. Knocked the noise down to a level that won’t get me kicked off the quieter tracks, which is exactly what I needed.

Finally, a straightforward fix for tracks with strict sound limits. The included rivets and gasket made installation clean, and it dropped the bark just enough to pass tech without killing all the low-end grunt.
