The aFe 49-38078-B MACH Force-Xp cat-back exhaust system delivers improved performance and an aggressive appearance for 2014-2021 Jeep Grand Cherokee WK2 models equipped with the 3.6L Pentastar V6 engine. In-house dyno testing produced gains up to +5 horsepower and +8 lb-ft of torque. The stepped 2-1/2" to 3" mandrel-bent 304 stainless steel tubing increases exhaust velocity for a broader torque curve throughout the RPM range. A high-flow stainless steel muffler combined with dual resonated mid-pipe produces a powerful, deeper exhaust note without annoying freeway drone. The muffler features a high-temperature powder-coated metallic black finish for long-lasting corrosion resistance and appearance. Dual angled, double-walled 4-1/2" black exhaust tips with laser-etched aFe POWER logos provide a bold, aggressive look. This CAD-designed system utilizes factory mounting locations and OE-style bayonet hangers for a hassle-free bolt-on installation with leak-free 360-degree sealing. Does not require CARB EO# for 50-state legal operation. Engineered and manufactured at aFe's facility in Corona, California.
