The Formula Dynamics Weld-In Sport Cats are a very cost effective way to replace your restrictive factory catalytic converters which are known to fail and potentially cause damage to your engine. Our Sport Cats allow significantly improved flow over their factory installed counterparts. You'll instantly feel the increase in Torque and Horsepower as well as a bit of volume increase.

** Please note that it is illegal to remove a properly functioning catalytic converter and that aftermarket catalytic converters are not legal for installation in California on OBD II vehicles.
