Large Bore-HD exhaust systems are the perfect combination of performance, fit and value. Single To Dual Exhaust Conversion: This exhaust is designed to convert the standard single exhaust into an aggressive dual exhaust. Fits With Spare Tire: This exhaust system fits perfectly without relocating the spare tire. OE Fit: OE-style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The bayonet tip holds the hanger bushing in place for an OE-style fit that does not change with time.
