Catback exhaust systems are a popular upgrade for 1979-1993 Fox Body Mustangs. They offer an increase in horsepower and a custom exhaust sound. While the factory set-up sounds good, its restrictive configuration leaves power and volume on the table.
Plus, catbacks are relatively affordable and easy-to-install. You'll have to do some cutting, but an exhaust shop can take care of the job for you if you don’t have the tools or experience. Each kit includes the clamps and hardware needed to fit onto your existing pipes.
Brands like Borla, Flowmaster, and MagnaFlow offer different options to suit each enthusiast. There are a variety of volume levels and exhaust notes to choose from. Some are quieter and are just a bit louder than stock. Others have classic a muscle car rumble or a European-inspired growl. By getting rid of the resonator, many cat-back kits offer much louder acoustics.
If you only want to optimize your exhaust sound, axle-back kits are the way to go. They're more affordable than cat-backs, and you can get the exhaust note and volume you’re looking for.
