5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
wut kind of exhaust system should i put on my 89' 5.0 HO? shuld i go wit the flowmaster mufflers? i want sumthing that will give me the most power and the loudest growl
Most people put on flowmaster systems. There pretty loud and sound very clean and deep, but if you want the loudest then go with SLP's Loudmouth system.
I liked my Flowbastard cat-back just fine for ease of installation & fitment. But maybe I'm getting old; I had to swap out the mufflers for quieter glass packed units...... Drone is no longer in my vocabulary....
