Replaces the restrictive factory catalytic converters with a straight-through “straight-pipe” design for maximum power, increased throttle response, and an aggressive exhaust sound

Includes two downpipes, labeled left side and right side for easy installation, and hardware

NOTE: Catbypass downpipes are recommended for track or off-road use only.
Please also bear in mind that this system does not include catalytic converters, so the Check Engine Light (CEL) will most likely be triggered. This is not an indication of any actual issue with the engine, and does not prevent normal vehicle operation.
