Thus, removing as much exhaust flow restrictions will increase horsepower and torque significantly. The factory catalytic converter found in the factory downpipe is a big culprit of this and is a major exhaust flow restriction. The factory catalytic converter is made up of catalyst material formed into \"honeycomb\" weaves. Exhaust gas must pass through these tiny \"honeycomb\" weaves on their way to the exhaust system thus causing a major exhaust flow restriction. It also causes turbulence after the catalytic converter which causes the exhaust flow to slow down (which increases restriction). By replacing the factory downpipe\/catalytic converter with our Sports Series High Flow Metallic Catted Downpipe, more power is unleashed!We use a 200 cell metallic core for our Sports Series High Flow Catted Downpipes. By having less cells per square inch, these individual \"cells\" are bigger in size thus allowing exhaust gas to pass through it more easily. Thus, the lower the cell count, the higher the flow. Higher flow = more power, faster turbo spool up (less turbocharger lag) and better throttle response. Bottom line, faster. The benefits of a metallic catalytic converter vs a ceramic like the factory is that it can take higher temperatures and is more durable (last longer). They are also lighter than their ceramic counterparts.Our Sports Series High Flow Catted Downpipes is constructed out of 100% 304 grade stainless steel and utilize mandrel bent piping. They are 100% TIG welded by our in house fabricators and built in the USA. The factory turbocharger turbine housing utilizes a 3.5\" V-Band flange which we have duplicated and CNC machined cut out of billet 304 stainless steel. Stainless Steel CNC machined O2 sensor and laser cut brackets are TIG welded using stainless steel rods. The O2 sensor is positioned at the factory location. 100% bolt on.Our downpipes are designed to fit perfectly with either the factory exhaust system or your aftermarket exhaust system. There are no compatibility issues whatsover. The downpipes will come by default with brushed finish.The S68 Engine has 2 primary catalytic converters and 2 secondary catalytic converters for a total of 4 catalytic converters. Our Sport Series High Flow Catted Primary Downpipes replace just the primary section. You can retain the factory or aftermarket secondary downpipes.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures :\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eHigh Flow 200 cell metallic catalytic converter\u003c\/li\u003e\n\u003cli\u003eHigher Max Horsepower Power Curve\u003c\/li\u003e\n\u003cli\u003eHigher Intial Torque Curve.
