Product Details

This MagnaFlow 14156 muffler is a straight-through design, meaning it has a perforated core that allows exhaust gases to flow freely. You get the muffler itself, which has a 4x4x6 inch round body and 2.5 inch diameter inlet and outlet ports on the center line. It’s made entirely of stainless steel, so it’s built to resist corrosion and last a long time. The straight-through design is what helps it produce that signature MagnaFlow sound and can improve exhaust flow compared to stock mufflers.

Because it’s a universal muffler, it offers flexible installation options. The 2.5 inch inlet and outlet are on the center of the muffler body, and it’s reversible, so you can install it in either direction. This muffler is constructed using advanced manufacturing techniques and features a brushed finish. MagnaFlow backs this muffler with a limited lifetime warranty, which speaks to their confidence in its durability.

Professional installation is recommended for this part. While it’s designed to fit a wide range of vehicles, you'll want to confirm that the 2.5 inch inlet and outlet sizes and the 4x4x6 inch body dimensions will work with your specific exhaust system's layout and spacing requirements.
