For a long time, the engine type could be recognized immediately by the sound when starting, during normal driving and especially under load. But nowadays this is hardly possible. Even a V8 is often so quiet from the factory that you don't know whether it's a three-cylinder or a four-cylinder or even a hybrid. With a CutOut system that is over, because the rear silencer is bypassed and everyone can hear what's going on under the hood. This gives you the engine sound of a racing car at the push of a button. In order to achieve an even better result, the bypass can be placed further towards the motor.
available for almost every system
There are many designs. That's why researching which CutOut system fits my vehicle is the most important thing. If the structural conditions of the vehicle permit, you can even do without welding. A piece of the exhaust pipe z. B. cut out in front of the rear silencer. Exactly the length of the piece is determined by a kind Y pipe replaced. The exhaust gases are practically branched off in front of the silencers and released into the wild. The branch can then be either closed or opened with the flap control, as required.
The exhaust gases either take the regular route through the rear silencer or the route with the better sound to the outside. Basically, the system is nothing more like a conventional flap system with remote control for the rear silencer. Many CutOut systems are equipped with a remote control, so the exhaust flap can be controlled remotely. Before doing this, however, you should think about where the bypass will be positioned in order to be able to safely lay the power supply for the damper. There must also be enough space for the recipient, e.g. B. near the fuse box. The remote control fits comfortably on the bunch of keys.
Installation is generally not difficult
You can also do this to save space. To do this, the bypass, with all the clamps, is placed at the desired point on the exhaust pipe and that's it. It's basically not science! If everything fits without hitting, the spot is marked exactly. In order to be able to work properly, the exhaust must now be removed. The marked area is now cut out. A router is used for the corners.
The bypass is then welded or alternatively screwed onto the opening (depending on the system). When that's done, the exhaust is reinstalled. Now just flange the electric exhaust flap and lay the power supply. Before finally tightening, make sure that the exhaust gases are not directed anywhere on the body. Remember: The closer the bypass is to the engine, the hotter the exhaust gases and the louder the result.
What are the benefits?
Depending on the version, it brings an increase in engine performance of up to 20 hp, since most engines react positively to the lack of back pressure. With the engine sound you definitely stand out. And you can switch back to series production at the touch of a button. Caution: If the selected CutOut system does not have approval for the vehicle, the general operating permit expires. Use on public roads is not recommended.
