Description
Overview
The Flowmaster Flow FX Cat-back Exhaust System is a bolt-on performance upgrade engineered specifically for the 2005–2015 Toyota Tacoma equipped with the 4.0L engine. Designed to deliver a deeper, more aggressive tone while unlocking better flow, this complete cat-back kit replaces your restrictive factory piping with mandrel-bent tubing and Flowmaster’s proven straight-through muffler technology. It fits both 2- and 4-wheel drive models and all wheelbases, making it a versatile choice for nearly any 4.0L Tacoma owner looking to add sound and style.
Built to Last
The system is manufactured from bright 409S stainless steel for years of trouble-free service, giving you corrosion resistance and durability that stands up to daily driving and the elements. A 2.50-inch inlet pipe feeds directly into the Flow FX “straight-through” muffler, promoting strong airflow for great sound and maximum performance. The muffler measures 20 inches in overall length with a center inlet and center 2.50-inch outlet, delivering a moderate, performance-tuned sound level that adds presence without being overwhelming.
Custom Look, Serious Sound
The mandrel-bent tailpipe exits behind the rear passenger-side tire and is capped with a large 3.50-inch diameter tip in black ceramic-coated 304S stainless steel, complete with an embossed logo. The result is a custom appearance that pairs perfectly with the deep, throaty tone of the Flow FX muffler. The silver pipe and muffler finish gives the whole system a clean, understated look under the truck, while the black tip makes a bold statement at the rear.
