About this part

Product Details

Magnaflow is well-known for making exhaust components that give your vehicle a signature sound and improved performance. This 18-inch long, 5-inch by 8-inch oval muffler, part number 12266, is a prime example of their approach. It uses a straight-through perforated stainless steel core, wrapped in mesh and acoustic fill, to let exhaust gases flow freely while producing a smooth, deep tone. This design is dyno-proven to help your engine breathe better.

The muffler body is made entirely of durable, corrosion-resistant stainless steel, so it's built to last. It features a satin finish and a weight-optimized body, which can be a nice touch for your exhaust setup's appearance. Because it's bi-directional, you have flexibility during installation, though professional installation is recommended. The inlet and outlet pipes are 2.5 inches on one side and 2.25 inches on the other, offering versatile fitment options for custom exhaust work.
