Koenigsegg Proves You Don't Need A Straight Pipe Exhaust

Performance Exhausts Patented By Koenigsegg Make Big Power

Do straight pipe exhausts actually make more power? Are straight pipes actually beneficial? Koenigsegg makes crazy horsepower engines and vehicles, and they happen to be emissions compliant. So does your neighbor's Honda Civic really need a straight pipe to put down 150 horsepower at the wheels, and how how does Koenigsegg make 1000+ horsepower engines that also don't create terrible emissions? Koenigsegg has a couple exhaust patents up their sleeve.
Koenigsegg's brilliance comes down to how they employ the use of pre-cats within their exhausts. Pre-cats are used to help reduce harmful emissions while a car is still warming up, and the main catalytic converter is still cold. In this video, we'll break down Koenigsegg's first patent ever, the 'Rocket Cat,' as well as the patented exhaust used on the Koenigsegg Agera RS. Check out the video for a full explanation!

    I’m curious whether other manufacturers use this tech in consumer autos, and if so, do they pay for the patent use. Thx!

    Wait, after he explained the issue i immediately though why don't they have a valve that that opens the MC and closes the PC once the engine is warm enough,similar thing is there for all cars for engine cooling and was there for long time, it is kinda obvious... so why did it take a "genius" to think about it?

    Somehow my Duramax lost its factory exhaust and got straight piped. Also, somehow, the emissions control devices also fell off. What a shame. Thankfully I live in a free state that doesn't do emissions testing.

    Am I the only one who wonder why manufacturers does not use electrical resistances in a wide mesh pattern inside the exhaust system to get the work temperature instantly and on demand for the exhaust section and engine temperature being wide enough to not be restrictive when off but enough to heat the gaps enough to burn the harmful particles 🤔

  • Federico Barrondo Hess

    Great video!! One question though: if in the traditional catalytic coverter the exhaust gases have to always go through the pre cat, then the exhaust flow is determined by the size of it and not the size of the main cat. Wouldnt it then make more sense to simply place the main cat closer to the engine exhaust so it works both in cold and warm start ups? I imagine the reason for that is that the pre cat is not as effective as the main cat when at operating temp, but I would like to know your thoughts on this.

    The idea of by passing a restriction is not new specially in the exhaust department, what I really want to know is how are these bypass valves built and there mechanism, to build a valve that can withstand that amount of heat & pressure yet still work properly every time with the presence of carbon deposits, is actually what amazes me.

    10:10 short observation on that part: Just because the clutches can close in as little as 2ms, doesn't mean that the gearbox will shift with that speed, mainly because an upshift from 3 to 4 will require the second shaft to increase it's rotational speed. Koenigsegg will of course try it's best to minimise it's inertia, but that still makes it less straight forward than an upshift that won't change the relative speed of the second shaft to the input shaft. Which means that either every third gear shift will take considerably longer to complete than others, or that all gear shift times will be matched to the slowest one. But no continuous positive torque, which was something you have claimed

  • David Elliott
    David ElliottÅr siden

    David Vizard discussing valves and gas flow says exhaust gas inertia causes the cylinder to go negative pressure just after the exhaust valve opens. The inlet opens momentarily later so the incoming charge is pulled in by the partial vacuum created by the exhaust flow. Konisegg have the Freevalve engine which operates its valves entirely electronically. No cam, no cam belt, around 20kg weight saving on a 1600cc engine. Each exhaust valve has its own outlet pipe with only one going to the turbo. The other goes straight to the catalyst. The individual valve openings control how much boost is made. No waste gate. The cold engine keeps the turbo valve closed and retards the spark ignition. That puts flames down the exhaust to quickly heat the catalyst. The precast is not needed. There is also no throttle valve it’s all done by the engine valves. Check out the freevalve video.
