Downpipes - so that the turbo generates more and faster power
If more power is tickled out of the turbocharged car, then downpipes are a moderate solution. These downpipes are generally an important source of power in turbocharged vehicles. Downpipes are part of the exhaust system. They connect the turbo outlet with the catalyst. If the shape and flow rate of this pipe section are improved, the turbo will be a little more potent. Modified downpipes tuned to a turbocharger type, make the turbo to rev up faster and develop a little more power at maximum speed.
Some models improve performance because they simplify the path and thus increase the gas flow rate through the charger unit. They also have a different size and shape than the standard downpipe, which can also lead to a gain in performance. The best reason to buy a downpipe is so that the performance gain is noticeable over a wide range of RPMs. While it is generally accepted that installing a downpipe adds "only" 10-20 horsepower, this gain is noticeable whenever the turbo kicks in. This leads to a strong, clearly noticeable increase in performance.
Different types of downpipes give different results. The greater the separation between the gas in the so-called wastegate and the exhaust gas, the faster and more effective the total exhaust gas flow due to combustion. To achieve an increase in performance via the downpipe, engineers have come up with various technical solutions.
- The cheapest option is the blank plate downpipe, in which the wastegate is completely covered.
- A Bell Shape Downpipe is an open, bell-shaped tube that collects virtually all of the gas from the turbo and lets it flow into the exhaust. It is advantageous that this construction can be installed almost universally in almost every turbo vehicle. The disadvantage is the significantly higher price.
- Split Bellmountain Downpipe is a bell-shaped construction with a separator to separate the waste gases to the wastegate separately from the main exhaust gas flow. This component is used in special cases, for which a vehicle engineer should estimate the benefits.
- The Dual Design Downpipe also separates the exhaust flow from the turbo and uses the exhaust as wastegate. Due to this separation, the gases are not mixed immediately, resulting in a smoother exhaust flow.
Downpipes are usually offered with a staggered pipe diameter. Some manufacturers also refer to the maximum load, which is usually at least 300 to 400 PS. Generally there are two main types of downpipes. The Catted Downpipe and the Catless Downpipe, where the Catless is operated without a catalyst and is therefore not available in Germany. Catted downpipes can boost performance provided they replace a standard downpipe and are catalytically linked to an all-in-one unit. However, the performance increase is not as great as described, because modern catalysts react rather restrictive. Other modifications that provide additional performance enhancements include exhaust manifolds, power air intakes and electronic tuners that re-allocate ignition timing and fuel delivery. Nice side effect is the sound. Meanwhile, there are downpipes that are tuned to a special tone. As a result, the engine is either barely audible, or the sound is full and hard on the limit of what is allowed.
