APS 3" High Flow Stainless Steel Matrix Catalytic Convertor
APS has gone to great lengths to custom design the highest quality catalytic converter. Whilst there are a number of 3" catalytic convertors on the market that promise high performance, there are significant durability issues particularly at high horsepower levels. The APS cat is streets ahead and an important item when exhaust gas emissions on high power WRX vehicles are an issue.

With true 3 inch inlet/outlet connections, it features a high flowing 200 CPI stainless steel matrix packed in stainless steel mesh. No other aftermarket converter (and few O.E.M. pieces) are constructed to such a high specification level.
