Show original supplier description
The American Racing Headers MTC5-11178300LSNC represents a high-performance exhaust upgrade for the 2011-2014 Ford Mustang GT 5.0L. Constructed entirely from durable 304 stainless steel, they are built to withstand the demands of a high-performance vehicle. The primary tubes are 18-gauge, offering a balance of strength and weight, while the slip-fit collector attachment ensures a secure and leak-free connection. Proudly made in the USA, these headers reflect a commitment to quality manufacturing. This specific model is designed as an off-road, non-catted X-pipe system, indicating it is intended for competition or off-road use where catalytic converters are not required or permitted. Proper installation may require accompanying mid-pipes and careful consideration of emissions regulations in your area.
