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.
