Flowmaster 389-718173 Features:
Flowmaster’s FlowFX Cat-Back Exhaust System is engineered specifically for the Toyota Tacoma equipped with the 2.4L engine. Designed for both 2WD and 4WD models, this high-performance exhaust upgrade is built from durable 409 stainless steel to provide long-lasting strength, improved exhaust flow, and enhanced sound quality. A 3.00-inch mandrel-bent inlet pipe feeds into a straight-through FlowFX series muffler to deliver gains in horsepower, torque, and throttle response. The system uses dual 2.5-inch mandrel-bent tailpipes that exit behind the driver-side rear tire and finish with bold 4.0-inch black ceramic-coated 304 stainless steel tips, giving the Tacoma an aggressive custom appearance with improved ground clearance. Dyno-proven increases of up to 11 hp and 17 lb-ft at the wheels help unlock the truck’s true performance potential. Installation is simple thanks to the use of factory hanger locations, factory-style connections, all included hardware, and detailed instructions. Backed by Flowmaster’s Lifetime Limited Warranty.- Mandrel-bent 3.0-inch and 2.5-inch 16-gauge 409 stainless steel tubing maximizes flow and durability
- Large black ceramic-coated stainless steel tips deliver a premium custom appearance
- Complete hardware kit and factory-style hangers ensure easy, direct bolt-on installation
- FlowFX straight-through muffler provides an aggressive-to-moderate performance exhaust tone
- Dyno-tested gains of up to 11 hp and 17 lb-ft compared to the stock exhaust system
- Includes Flowmaster’s Lifetime Limited Warranty
- Tuned performance sound enhances the driving experience inside and outside the truck
