The kit includes the necessary flanges and hardware for a straightforward upgrade. Ideal for enthusiasts seeking to optimize their Mustang’s exhaust system for increased performance, this high-flow mid-pipe is suitable for street and performance driving, providing a more aggressive sound and improved exhaust flow without compromising emissions compliance.
