You will feel the difference instantly. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOur Competition Series Catless 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 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.  Since the outlet of the turbocharger is 3.5\" and the factory exhaust system is 3\", the factory downpipes reduces size using short transitions from 3.5\" before the catalytic convert and 3\" afterwards.  Due to space needed for the cataylic converter, the factory downpipes reduce in size using very short transitions.  Since our catless downpipes delete the cataylic converter, we have more space.  Thus, we use very long transitions.  These longer transitions allow the exhaust gas time to smoothly transition from the larger piping to the smaller.  Also, since we utilize a larger 4\" pipe right after the turbocharger, turbo backpressure is significantly reduced.  This results in less exhaust turbulence and backpressure which again improves throttle response and increase turbocharger spool times (less turbocharger lag). \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOur 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 in Brushed Finish.  We also offer a Polished Finish as an option.\u003c\/span\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOur downpipes are designed to fit perfectly with either the factory exhaust system or your aftermarket exhaust system.

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\u003cstrong\u003eAdditional O2 Sensor Bung - \u003c\/strong\u003eAn additional O2 sensor bung can be added so that you can easily add a wideband O2 sensor and gauges for you to monitor air\/fuel ratios.
