Handcrafted from US-made 3 T304L stainless steel, the 0FG Exhaust is a straight-through Cat Back configuration applicable to all Bronco models 2.3T, 2.7TT, 2-door and 4-door with modular capabilities unlike anything on the planet. The 0FG Exhaust features a bespoke AWE resonator in the mid pipe to produce an appropriate dose of aggression, followed by smooth bends towards the rear of the Bronco. On the way to the rear, depending on how many doors there are on your Bronco, lies an included adapter to bridge the difference in length across models. 2-door owner simply won't need these adapters, but 4-door owners will be thrilled. The 0FG modularity shines at the final breakpoint in the exhaust route. Not only does the 0FG accommodate various tip options, it also accommodates AWEs BashGuard. Whats BashGuard? Thanks for asking. The AWE BashGuard is included in every 0FG exhaust, and enables the 0FG to be the one exhaust to rule them all. Thanks to the modularity in the rear, simply remove the rear axle-back portion of the 0FG and replace it with the high-tuck BashGuard. BashGuard is appropriately equipped with a .125 thick reinforced stainless ring. Perfect for bashin. This version of the AWE Bronco Exhaust is the Single Side Exit: one big n proud 5 double-walled tip in chrome silver, straight-cut tip exiting behind the left rear tire, adding a dose of aggression to the Bronco you never knew it needed. One exhaust. Every terrain.AWE's No CEL Guarantee, Perfect Fitment Guarantee, and Lifetime Warranty come standard.
