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! \u003c\/p\u003e\n\u003cp\u003eWe 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.\u003c\/p\u003e\n\u003cp\u003eOur 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.\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eOur downpipes are designed to fit perfectly with either the factory exhaust system or your aftermarket exhaust system.  There are no compatibility issues whatsoever.  The downpipes will come by default with brushed finish.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe BMW XM (G09) has 2 primary catalytic converters and 2 secondary catalytic converters for a total of 4 catalytic converters.  \u003cstrong\u003eOur Sport Series High Flow Catted \u003c\/strong\u003e\u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003ePrimary Downpipes replace just the primary section\u003c\/span\u003e. \u003c\/strong\u003e\u003cspan\u003e You can retain the factory or aftermarket secondary downpipes.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eOPTIONS\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCeramic Thermal Coating -\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eThe purpose of ceramic coating downpipes is to keep heat from the exhaust gases inside the downpipe from radiating out. This keeps underhood temperatures lower and less heat absorption by nearby parts\/surfaces.  Another added benefit is that by keeping in heat (energy) in the exhaust gases inside the downpipe, exhaust flow velocities stay up, resulting in lower backpressure. The ceramic coating also adds additional corrosion resistance. We utilize the best ceramic coating possible. Our thermal coating can resist up to 2000F of heat. It is available in black only (all the other colors cannot withstand the high levels of heat).\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003e\u003cspan style=\"color: rgb(245, 4, 4);\"\u003eCAUTION\u003c\/span\u003e: \u003c\/strong\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003eThis product is intended for \u003cstrong\u003eOFF ROAD COMPETITION USE ONLY\u003c\/strong\u003e.
