The most restrictive part of any exhaust system is the catalytic converter. The stock catalytic converter is meant to filter the flow of the exhaust gases to reduce the amount of harmful gases into the atmosphere. That is a potential performance restrain. This front pipe eliminates the stock catalytic converter and reduce exhaust back pressure by maximizing exhaust flow Which gives a increase in horsepower. The result brings out the vehicle's performance potential by giving it a high free flow exhaust system.
