Flo-Pro 664NM DSL GM Down Pipe Back Kit

Flo-Pro Performance Exhuast delivers powerful results to your diesel truck. Founded in 1981, FLO~PRO Performance Exhaust has been manufacturing and distributing only the most durable quality muffler and exhaust systems for your vehicle... Hands down! 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.
