PLM Power Driven Titanium Y-Pipe for Nissan GT-R R35 GTRPLM Private Label Mfg Power Driven Y Pipe for Nissan GT R R35 was made for maximizing HP gains. The Y Pipe generates more horsepower by optimizing engine airflow and volume through carefully selected, application specific tubing lengths and diameters and increased wave scavenging effects for more horsepower. CNC mandrel bending allows for a constant tubing diameter throughout the bend, which results in precise fitment as well as improved exhaust gas
