Exhaust cutouts are a unique way to have a loud exhaust and a quiet exhaust that you can quickly switch back and forth to. With a set of exhaust cutouts, you can have one end lead to your OEM exhaust and the other end lead to a straight pipe. Although installing cutouts can be more expensive than installing a standard exhaust, the convenience of being able to switch back and forth between exhaust notes is worth it.

Built at our own state-of-the-art manufacturing and testing facilities, ROUSH parts and vehicles will get you to the intersection of style and performance.
