Founded in 1981, FLO~PRO Performance Exhaust has been manufacturing and distributing only the most durable quality muffler and exhaust systems for your vehicle. FLO~PRO has proven it beats the competition with louvered pipe that accelerates the exhaust flow through our mufflers. FLO~PRO performance mufflers are designed to boost the horsepower generated from your street vehicle. The 100% aluminized steel welded construction will outlast conventional locked-seam, double wrap mufflers. The louvers also give a deep performance sound without the use of fiberglass that would eventually blow out! We also specialize in Diesel Performance carrying full systems for virtually every diesel truck. Want to know more about how they sound?
