Flowmaster Outlaw Extreme Exhaust Systems

4.79 out of 5 stars 24 Customer Reviews

Flowmaster Outlaw Extreme exhaust systems provide maximum sound level and performance. These race-oriented systems feature 409S stainless steel construction—and their small, lightweight Outlaw mufflers. The mufflers generally produce more power than open headers, while taking "the edge" off the open-header sound, but still producing very aggressive tones, both inside and outside your vehicle. Flowmaster Outlaw Extreme exhaust systems are race-proven and the perfect choice at race tracks requiring mufflers, but without dB restrictions.
