I am trying to do some upgrades to my stock 98 automatic mustang gt. I am going to change the exhaust, but what should I do next? What is the difference between short and long headers? are they easy to install?

 

the only advantage to short tube headers is you can use the facory length mid pipe. Long tubes will have a much more noticeable gain in power but require a new midpipe as well. Long tubes are also a pita to install.

 

long tubes sound better
