Tapper Velocity Back Pressure (32/32/32mm) is the leaner-flow option across Y15ZR, Y16ZR and LC135 V1-V7. Back Pressure Standard offers larger sizing per model (35/38/32 on LC135 and Y15ZR, 35/38/35 on Y16ZR) plus three RSX sizes. LC135 official PNP fitment is confirmed for V1-V7 only; V8 requires custom cutting/modification for the Tapper Velocity version and must use the Y15ZR cover.

Replaces the stock exhaust; PNP fitment applies to LC135 V1-V7 as stated by the seller, while V8 and other applications need extra fitting work. Package contents beyond the exhaust system are not verified — check with the seller.
