Restrictions in the exhaust system robs horsepower 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 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 Metallic Catted Downpipe, more power is unleashed!
The factory catalyter uses a 600 cell ceramic core. What the 600 cells means is that per every inch, there are 600 "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 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 Competition Series Catless Downpipes is constructed out of 100% 304 grade stainless steel, even down to the included hardware. Utilizing mandrel bent tubing, each downpipe is 100% TIG welded by our in house fabricators and built in the USA. The factory wastegate outlet 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.
The factory turbocharger outlet has an iregular oval outlet as well as a very tight first turn. Reducing backpressure right at the turbocharger outlet is very critical for reducing turbocharger lag and a faster spoil up of the turbocharger. Due to the tight first bend, we felt we could not keep the correct shape to reduce restriction with regular tubing. Even the factory downpipe utilizes a formed piece instead of tubing. Thus, we decided to cast form stainless steel to produce the eact shape needed to maintain a smooth transition on the first turn. While this would dramatically increase development costs, we followed our company motto, "Performance, no Compromise" to offer you a much superior performance product.
Since the outlet of the turbocharger is around 4", we utilize 4" stainless steel tubing which using long transitions to reduce the size to 3" to match up with our 3" Evolution Racewerks Mid Pipes (factory is 2.5"). These longer transitions allow the exhaust gas time to smoothly transition from the larger piping to the smaller. This also allows us to keep a true 3" size through to our Evolution Racewerks 3" Mid Pipes as the factory mid pipes are 2.5". 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).

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 in Brushed Finish. We also offer a Polished and Ceramic Thermal Coated Black Finish as an option.
Ceramic Thermal Coating - The 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 absortion 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 high, resulting in lower backpressure. The ceramic coating also adds additonal 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).
Additional O2 Sensor Bung - An 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. The additional O2 sensor bung will come pre-installed with a plug so that you do not need to run the O2 sensor right away.
Optional EGT (Exhaust Gas Temperature) Bung - An additional 1/8" NPT bung can be added so that you can easily add a EGT sensor and gauge. The optional EGT sensor bung will come pre-installed with a plug so that you do not need to run the EGT sensor right away.
