I recently purchased a 89 Mustang LX and This is my first Mustang ever. I had a few questions, Is it possible to buy longtube headers then just bold up say a MAC pro-dump exhaust straight to the headers? Or with long tubes do you have to buy an x-pipe? What kind of exhaust would fit on a longtube application? If anyone has installed longtubes on a fox please let me know how hard it was and what brand to purchase! Thanks for your help guys!
