These N55 downpipes feature larger piping and catalytic converter that are freer-flowing than the original cats for better flow and less backpressure. By removing exhaust restrictions the turbos can spool up faster which makes more boost sooner. With additional tuning, more power is available. There are downpipes that delete the primary cats and can leave the exhaust with a dirty and awful smell. These Wagner downpipes are built with a sport cat to keep the exhaust cleaner.Special software, or stand-alone engine management, will be required to keep emissions fault codes and check engine lights from appearing.
Features:
For 2011 models, pick up a Cobb AccessPort programmer to go along with these downpipes. Additional tunes are available that will get the most out of this upgrade. Not only will the Cobb AP increase horsepower and torque but special programming is available to keep fault codes, check engine lights, and limp mode from disrupting your day. It has other features too such as data logging and diagnostic fault code reading and clearing. The Cobb AP is the most sophisticated programming tool available for the 135/335 and no tuning plan should be without one..

Wagner intercoolers (#200001044) are engineered in Germany to be a superior N54/N55 intercooler than the factory part. With 85% more surface area than the factory IC the Wagner-designed kit is much more efficient. And that helps maintain your boost levels and performance! The factory intercooler is quickly overcome with heat and that leads to a loss of boost and performance. Factor in greater boost levels and other modifications and the more heat soak will put you out of the running. The solution is an intercooler with more capacity for cooling and Wagner has chosen the stepped design to maximize the available surface area in the front end. The step is a thicker bar and plate core with an additional set of rows on top that takes advantage of unused space in the nose. In our eyes, the best intercooler upgrade is one that not only works but also installs with a minimum amount of fuss.
Compared to the stock OEM intercooler:
One of the best features of this kit is how easy it is to install (the easiest we have used to date). It's a direct bolt-on replacement for your stock intercooler - no removing the bumper or modifying brackets or wrestling with plumbing. Core size measures 520 x 210 x150 with a 13.6cm flow rate. Wagner has also engineered their end-tanks in aluminum instead of the factory plastic, which is much more durable over the long term. The CAD and FEM process also allows them to design their cooler internals without any bottlenecks or restrictions. This is just the best all-around intercooler upgrade we have seen for the E90 E92 335! Fits both N54 and N55 cars.
