Info

Outlaw mufflers are designed to be connected directly to the header collectors or can be added into an existing exhaust system. Recommended for racing applications where a muffler is required without a set decibel limit to be met. Please call the Flowmaster tech-line for assistance with specific dB requirements and applications.
Some parts are not legal for use in California or other states with similar laws/regulations
