طقم إدخال الصوت كاتم صوت AT2 ريس (INS-37-K)

The bigger outlet on this race muffler made instant sense once I heard the deeper bark from my YZF-R7 -- it's exactly what I needed for the AT2 system. Packed tight and fit perfect without any wrestling, just like the listing described.

Took about 15 minutes to swap in, and the non-spark arrested design gives it a noticeably deeper, more aggressive tone under acceleration.

Took a gamble that these would fit my titanium race system’s big outlet, and the 2.375” sizing is spot on. The kit came complete with everything needed, so swapping the old insert took under ten minutes. Engine sounds a touch rowdier now, exactly what I was after.
