SYS 05-12 TACOMA 4.0
This American Thunder® Cat-back system is designed for the 2005-2012 Toyota Tacoma with 4.0L engine. The system is constructed entirely of 409S stainless steel for long-lasting durability. The 2.50-inch mandrel bent system connects to the back of the factory catalytic converter assembly using the supplied flanged inlet pipe. It then flows into a Super 50™ Series performance muffler and exits into dual 2.50-inch stainless steel tailpipes, which exit on both sides of the vehicle behind the rear tires. The tailpipes are finished off with large 3.00-inch polished stainless tips embossed with the Flowmaster® logo. As an American Thunder system, it provides improved horsepower and torque along with a moderate performance sound level both inside and outside of the vehicle. Includes instructions and all necessary hardware for an easy bolt-on installation you can do at home and is covered by our Lifetime Limited Warranty. Note: Does NOT fit standard cab or X-Runner models.
