What is the difference between shorty and long tube headers? Which should I buy?
Both shorty and long-tube headers are available for GTs and Cobras. Short tube headers make more power than stock manifolds but less than a long tube header will. The short tubes are the same size as the stock manifolds so you can use the rest of your existing exhaust system. Longtube headers make more torque and power but installation is much more involved. The headers extend down to the transmission and require a specific short matching h pipe. If you can, get the longtubes they will increase your torque and HP more than shorties will but they cost more.
