MSA Performance Exhaust Systems

These tuned exhaust systems are engineered for minimum back pressure and efficient exhaust scavenging. The high efficiency "Turbo" style muffler ("turbo" refers to the designed flow of the exhaust through the muffler, not to a turbocharged engine) provides this reduced back pressure without the harsh volume of many other types of performance exhaust systems. 2-1/2" pipe size (300ZX uses 2 1/4"). They can be installed directly to our 3-2 header on your 70-78 Z. They also are great options for your Catalytic Converter equipped 1975-1983 Z or ZX. Requires no welding. Kit includes all parts necessary for installation, and a chrome tip!
