Flowmaster 389-818177 Features:
Flowmaster’s Outlaw Extreme Cat-Back Exhaust System is built for Toyota Tacoma models equipped with the 2.4L engine and constructed entirely from durable 409 stainless steel for long-lasting strength. The system features 3.00 in. mandrel-bent tubing designed to increase exhaust flow, sharpen throttle response, and improve overall performance. A race-inspired Outlaw Series muffler produces an aggressive, high-impact exhaust tone both inside and outside the truck, making it an ideal choice for drivers seeking maximum sound and performance. The system exits beneath the vehicle with a dump-style turn-down tip that enhances ground clearance—an advantage for off-road driving. Dyno testing shows gains of up to 9 hp and 14 lb-ft at the wheels. Installation is simple with factory hanger locations, included hardware, and detailed instructions. Backed by Flowmaster’s Lifetime Limited Warranty.- 3.0 in. mandrel-bent 409 stainless steel tubing improves exhaust flow and long-term durability
- Turn-down dump-style exit increases ground clearance and produces an aggressive exhaust note
