SOUND INSERT KIT FLARED for ALPHA and ALPHA T Mufflers (INS-27-K)

2026 ZX10R

Running the 3/4 AT2 system on my tuned 26 ZX10R is a bit raw for my ears on the street. Installed the included INS-20-K DB killer... Meh, pops were tinny, tone was raspy. The INS-27-K is great, calms down the cold starts, keeps the deep tone, keeps the pops deep and and not tinny, no drone, no rattling/vibrating like the interwebs would have you believe. Gotta say, this insert is choice. 10/10 would recommend to anyone

Great sound.

Easy to install. Really nice sound.
