If your RX-7 no longer needs emission compliance and maximum power is your plan, then this is your solution. Meticulously designed to replace the factory main converter. It will bolt to any standard catback exhaust and downpipe. The stainless presilencer makes a major reduction in exhaust note. Obviously this is not an emissions compliant product and is intended for off road competition use. Also, please make sure the car has been prepared for the exhaust flow change (programmable engine management, enhanced fuel pump, better injectors, etc.). 

• Over 19 pounds lighter than stock (19.3 lighter (11.8 v 31.1))
• All stainless-steel construction
• Direct bolt in design
