Great set of cats for the Z

These guys sound amazing! Excellent build quality and helps get rid of that good ole trumpeting Z note. Comes with all hardware including O2 bungs, and gaskets. Shipping time was lightning quick. Dane is always the G.O.A.T. when it comes to orders!

The beast

They fit perfectly and come with all the hardware and gaskets needed. It did help quiet the car down some because straight pipes, but would definitely recommend for a cat replacement
