The Durango is a potent performer as delivered. This year, Dodge ups the antewith its remarkable Hemi 5.7L engine and a stunning facelift. MagnaFlow makes a great thing even better with its cat-back performance exhaust system that delivers a smooth, deep tone and a nice bump in power and torque. Our standard Durango systems offer 3" piping with a rear exit 3.5" tip, and you can expect gains of about 23 HP and 32 Lb-Ft of torque. Backed by a lifetime warranty.
