“AWE has a commitment to producing 50-state legal exhausts, and our Gen2 F8X Exhaust offerings achieve just that,” said AWE vice president, Jesse Kramer. “We accomplished a very tricky task, not once… but twice, and that’s making the S55 sound radical. This time, drivers will have the peace of mind of keeping all of their catalysts in place while also unlocking the performance and sound AWE is known for.”

The exhaust suite will feature AWE’s valved SwitchPath Exhaust that retains all factory valve behavior and their Track Edition Exhaust for those who are looking for maximum aggression and weight reduction.
