Unlike many of our competitors, our cats just like our test pipes will bolt on easier with 2 factory style studs used in each of the top flanges rather than just nuts and bolts, making install a breeze.
Fit '03-06 350Z, '03-06 G35 Sedan, '03-07 G35 Coupe models equipped with the VQ35DE (Single Throttle Body) engine.
