Hey guys has anyone here tried and dynoed a kreissieg exhaust? If so what power did you get out of it? Cheers
I went right to the first clip. One of my favorite exhaust sounds on video: http://www.youtube.com/watch?v=_UWVxT7YcFw&feature=related http://www.youtube.com/watch?v=LW5Xne1MVyQ&feature=related _J
I, too, am interested in chatting with someone who has the Kreissieg system on a 360 Spider and where they had bought it.
The only two dynos I've seen on them over the years (Gallardo & Porsche Turbo) showed power LOSSES in both open and closed configurations. The tubes were just too small. You buy them strictly for the sound.....
What about the ultimate which is the top of the line product, it has 60mm pipes which are 2.36 inches, what do capristo, tubi etc have?
Ive seen different on an independent dyno test. The Gallardo exhaust made power in open mode, but lost a fair amount in closed mode. They are near straight pipe in open mode, so they definitely wont lose power.
They will if the tubes are too small, the butterfly valve is too small, and have too many bends, this is what the Porsche engine builder told that guy. It was creating too much backpressure. I liked the thought process though, since it was the only switchable system then that had the bypass pre-cat. Anyone buying one needs to press for proof if you're looking for HP gains. When I TRIED to press them 4 years ago, they were so evasive I finally gave up trying......along with getting the two pieces of feedback.
Don't really know anything about the pipe sizes...but this is the best sounding exhaust I've heard on a 360...at via a video clip.
I checked this morning both exhausts use 60mm piping, capristo and kresisieg. Capristo has extremely high quality and kreisseig sounds so very unique. Its a tough call. If you need a quote let me know. Rob
Hello. With valve open mode, our system DO produce better response and increase power. We do not post specific dyno data because many exotic cars put wide range of power figures heavily depending on the engine conditions. Kreissieg has been making valve system exhausts for more than decades. With Motorsport orientated spirit, our exhaust product produces very unique sounds which resemble F1 car. With world class craftsmanship and our know-how, we always aim for producing the best valvetronic exhaust system. There are many valve operated exhaust system in market(even some OEM cars), but our products are NOT just another valvetronic exhaust system because of many reasons. Our concept really concentrates on exhaust tone which is actually controlled by inner design of the mufflers, and different material and thickness of stainless steel used and ect. The valve system is just a part of our unique sound. It only does changing the loudness. There are many variables that can change the exhaust tone of the engine, and we have been creating our own exhaust tone with our own knowledge. If one system does not meet our standard on sound quality, we keep make revisions on muffler, piping and ect to achieve our own exhaust tone. For some cars, we made up to 9 major revisions. (F360 being one with many updates) The valve system itself differs from other company's unit too. It is all about who makes more reliable and more free flowing valve. Kreissieg has our own know-how to make less restrictive and reliable valve system. We have up to 90mm diameter valve system without any reliability issue. The diameter plays big role when it comes to valve reliability because some of exotic cars exhaust temp gets so high, the butterfly usually glow red after some runs.(one of reason why Ferrari uses small diameter butterfly on their exhaust systems) If the valve designed poorly, the butterfly will stuck after these hot runs. We also use vacuum operated valve for exhaust system for reliability too. Not only our system offers reliable valve operation, but our valve itself is also slightly larger than the piping to compensate the restriction of center section of butterfly when it is fully opened. These are just very few things I would like to let our customers know. Little details like this make our exhaust system stands out from all the valve-controlled exhaust system. Feel free to ask us any questions regarding our product. Thank you. Jae
What size piping does a standard system have and what size is the kreissieg, not the valves but actual system piping.
For piping(not the valve), F360 main piping is 60mm and divides into two 45mm(one being valve controlled) Our system also uses 60mm for main piping but we use two 50mm pipings for valve section area.
Sorry currently we do not have video clip from CS. But both CS and Modena sounds very similar once our exhaust being installed. For F360, our system makes really good sound. We still have F360 as our own R&D car and that's how we were be able to make many revisions to achieve the "best sound" More videos can be found here.(older versions) http://www.youtube.com/view_play_list?p=69F61E5D8A74C470
I understand that the valves on the Kreissieg is remote controlled. That aside, would the valves also operate automatically once the engine speed reaches a certain RPM like a stock 360/CS exhaust? Or do they operate ONLY via the remote control?
It operates only with remote control simply because the loudness between two mode are significant. The installer can simply make it so that it works with OEM system, but most user actually prefer to control individually.
