Compatibility

Yamaha Y16ZR (exact version fitment not verified, confirm with seller)

32/32/32: 32mm manifold, the smaller size, generally chosen for standard or lightly modified Y16ZR engines. 35/38/32: 35mm manifold with a larger 38mm mid section, generally chosen for modified engines such as a bigger bore block, ported head, larger throttle body and racing cam. A pipe too large for a standard engine can reduce low and mid range pull. Final choice should match your engine build and tuning.

Replaces the stock Y16ZR exhaust. Professional installation is recommended. ECU tuning is recommended after installation, especially on modified engines. O2 sensor port and package contents not verified, please check with the seller.
