Compatibility

Yamaha Y15ZR - seller states it is designed around an LC-spec head, not the stock Y15ZR OEM head

Two diameter options are offered; pick based on your engine build and desired tone. Per the seller, this exhaust is designed for use with an LC135-spec cylinder head rather than the stock Y15ZR head - riders on a standard Y15ZR head should confirm compatibility first.

Package includes one exhaust unit. The seller notes the inner cover may need minor trimming to clear the pipe, or an approximately 20mm boost spacer can be added instead; installation should be done by an experienced mechanic.
