Got this to replace the old car back I had which the tip fell off. It looks awesome out of the box but not as well on the car. It looks ugly, hangs very low and is a bit sideways. Also because it's an under axel design, if you lift the car the axel pushes down on it. Hopefully some Cusco hanger can fix these problems if not I will be changing the cat back in the future. Combined with the box SS header and a T3 test pipe it's very really loud. It does have a small resonator but it's more for keeping some low end torque not for resonating. It may bother others but it's music to my ears.
