# MagnaFlow 17121 Off-Road Pro Series Cat-Back Stainless Exhaust System for 2004-2006 Jeep Wrangler

### Performance Overview

The Magnaflow Off-Road Pro Series Exhaust System is crafted from T-409 stainless steel for maximum durability. It includes a satin finish stainless steel muffler that has a straight through design. It gives great flow and a powerful tune. The Off-Road Pro Series has a hidden exit that sets it apart from the rest. It uses a turndown tip that exits before the axle, and avoids the extra length and bends allowing your engine to give out an aggressive tone. The Magnaflow Off-Road Pro Series Exhaust System uses mandrel-bent pipes for smooth and continued exhaust flow to maximize performance gains. The Off-Road Series is versatile and can take almost all engine layouts.
