Yoshimura's ALPHA T race exhaust for the 2015-on YZF-R1: a stainless mid-pipe and tailpipe into the tapered ALPHA T muffler, in Works Finish stainless with a carbon fiber end cap. It is 10.3 lb lighter than stock, and the tapered sleeve gives a higher, GP-style note than the full-size ALPHA.
Fits Yamaha YZF-R1 2015–2025
