Flowmaster 389-718174 Features:
Flowmaster’s FlowFX Cat-Back Exhaust System is designed for Toyota Tacoma trucks equipped with the 2.4L engine and fits both 2WD and 4WD configurations. Constructed from durable 409 stainless steel, this system improves exhaust flow, enhances durability, and delivers a deeper, more refined performance tone. A 3.00 in. mandrel-bent inlet pipe feeds into a straight-through FlowFX Series muffler, sharpening throttle response and maximizing overall performance. Dual 2.50 in. mandrel-bent tailpipes exit behind the rear tires, improving ground clearance compared to the factory design. The system is finished with large 4.0 in. black ceramic-coated 304 stainless steel tips that provide a bold, custom appearance. Dyno-proven gains of up to 12 hp and 14 lb-ft at the rear wheels highlight the performance benefits. Installation is simple thanks to factory hanger locations, factory-style connections, all necessary hardware, and detailed instructions. Backed by Flowmaster’s Lifetime Limited Warranty.- 3.0 in. and 2.5 in. mandrel-bent 409 stainless steel tubing enhances durability and maximizes exhaust flow
