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.

The tailpipes are finished off with large 3.00-inch polished stainless tips embossed with the Flowmaster® logo.
