Restrictions in the exhaust system robshorsepower and torque especially on turbocharged 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 exhaustsystem thus causing a major exhaust flow restriction. It also causesturbulence 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 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 housefabricators and built in the USA. The factory turbocharger turbine housing utilizes a 3.5\" V-Band flange which we have duplicated and CNCmachined cut out of billet 304 stainless steel. Stainless Steel CNC machined O2 sensor and laser cut brackets are TIG welded using stainless steel rods. From the factory turbo outlet of 3.5\", our downpipe expands to a full 4\" Piping. 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. This results in less exhaust turbulence and backpressure which again improves throttleresponse and increase turbocharger spool times (less turbocharger lag).
The 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 affects right away, over time, the stresses causedby 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. Withouta flex, you can imagine how much stress is put into exhaust components like the exhaust manifold/turbocharger 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.
