The turbine emissions process produces a vortex effect which purifies the exhaust gases while maintaining an equal amount of back pressure. When compared to a variety of conventional straight downpipes, the patented eddy catalytic technology can effectively increase horsepower and torque. In the lower rpm you will be immerse with vast amount of torque until you reach higher rpm where the vortex effect really comes to life and opens up the Catalytic, resulting in a performance similar to a 100 CELL Catalytic.

cars.  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 4\" High Flow Catted Downpipe, more power is unleashed! \u003c\/p\u003e\n\u003cp\u003eThe factory catalytic uses a 400 cell ceramic core.  What the 400 cells means is that per every inch, there are 400 \"cells\" that the exhaust gas must pass through.  We use a 200 cell metallic core.  By having less cells per square inch, these individual \"cells\" are bigger in size thus allowing exhaust gas to pass through it more easier.  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 more heat and is more durable (last longer).  They are also lighter than their ceramic counterparts.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOur Sports Series 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 4\" 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 4\" and the factory exhaust system is 2.5\", the factory downpipes reduce size using short transitions from 4\" before the catalytic convert and 2.5\" afterwards.  Due to space needed for the catalytic converter, the factory downpipes reduce in size using very short transitions.  Since our catted downpipes utilize a s more compact catalytic 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.  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\u003eThe factory downpipe utilizes a flex bellow section that allows the exhaust system to move.  This eliminates undue stress on the exhaust components like the exhaust system, downpipe, turbocharger and exhaust manifold.  Many of our competitors do not feel it is important to keep this.  While you do not see any adverse effects right away, over time, the stresses caused by not having a flex section and having a rigid exhaust system will cause premature wear and tear.  Any stress failures like cracks will form quicker than usual on exhaust manifolds and exhaust components.  Also, without a flex section, the exhaust system cannot properly deflect impact.  Especially on lowered cars, whenever the exhaust system contacts the ground, the entire system gets pushed up.  Without a flex, you can imagine how much stress is put into exhaust components like the exhaust manifold when the exhaust is pushed upwards.  We fully understand that durability of our products is important.  Thus, like BMW, we incorporate a flex section into our downpipe.  Our flex sections are 100% stainless steel (cheap flex sections only have stainless steel center braids and steel caps) to ensure corrosion resistance.  \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOur downpipes are designed to fit perfectly with either

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 Competition Series 4\" Catless Downpipe, more power is unleashed! Our dyno testing has shown around 14-16whp average peak gains and upwards of 24wtq peak gains! While peak horsepower is nice to look at on dyno charts, what's more important is the power curve. If you look at the dyno charts, torque hits \u003c\/span\u003e\u003cstrong\u003eMUCH\u003c\/strong\u003e\u003cspan\u003e earlier and harder.
