MagnaFlow #19546 is weight optimized for additional utility and designed such that its mandrel bent 2.5” diameter main piping is situated more closely to the body than the stock configuration. This combined with a single high-clearance no-tip, passenger-side rear exhaust exit allows for significantly improved ground clearance and departure angles. MagnaFlow exhaust system #19546 is compatible with the most popular bolt-on aftermarket modifications and features our No Drone Technology, which cancels out the natural droning frequencies of the V6 Toyota 4Runner at cruising speeds. This allows for a quiet ride on the highway while retaining the character of your rig’s exhaust note. CNC precision robotic manufacturing enables perfect fitment and hassle-free bolt-on installation. The 100% stainless steel construction of exhaust kit #19546 is covered by MagnaFlow’s limited lifetime construction warranty.
