Flowmaster FlowFX Cat-Back, Dual Side Exit Exhaust For 1999-2006 (and 2007 Classic) GM 1500 Trucks (Crew Cab and Extra Cab)
Flowmaster’s latest FlowFX Cat-Back Exhaust System is for the 1999-2006 (and 2007 1500-series Classic) with the 4.3L V6, 4.8L V8, or 5.3L V8 in trucks that are either Crew Cab with the 5.5-foot bed, or the Extra Cab with the 6.5-foot bed only. This exhaust is manufactured using durable 409 stainless steel throughout and features a 3.0-inch to dual 2.5-inch mandrel bent pipe layout for better exhaust gas flow. A FlowFX “straight-through” muffler is used for a moderate to mild sound level and maximum performance. Maximum increases on the dyno revealed +14 horsepower and +13 ft-lb at the rear wheels. This system exits on the passenger side, before the rear wheel with dual 4.0-inch black ceramic tips for added style and a custom look. The system uses all the factory hanger locations and includes installation instructions and all necessary hardware for an easy installation that you can do at home.
Backed by Flowmaster’s Lifetime Limited Warranty.
