In recent testing this system produced 18 horsepower and 30 lbs. x ft. of torque. This unique exhaust system is constructed from TIG-welded, 3 in. mandrel bent 304 stainless steel and uses quad, high-flow mufflers. This system was designed and engineered by tuning the perfect tube lengths, ultimately maximizing performance across the power band while maintaining a great tone. Also included is an X-pipe balance tube which equalizes and evenly distributes exhaust pulses for increased flow and minimizing exhaust drone. To finish off this system, aFe uses four 4 in. carbon fiber tips with 303 stainless steel machined finish inserts. This exhaust uses all factory hanger locations for a hassle-free installation.  No modifications necessary. All aFe exhaust systems are manufactured in our Corona, California manufacturing facility.\u003c\/p\u003e\n\u003ch4\u003eFeatures \u0026amp; Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3 in.
