The perfect option for track cars and those who seek the ultimate in agressive exhaust sound
Mandrel bent pipes with minimal welds to minimize failure under regular use and increase flow

This product replaces the factory catalytic converters and may trigger a Check Engine Light.
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.
