HKS Stainless Steel Y-pipe, VQ35DE - Nissan 350Z / Infiniti G35 RWD

It's more big in pipe diameter which let the exhaust gas smoothly to the muffler and have better engine performance. More torque at mid to high RPM by connecting left and right bank with bypass pipe. We used SUS304 that has durability and great appearance. We have checked with HKS Supercharger Kit testing.
