well, as expected, an "expert" made another inaccurate post on a different website, using somebody's home made website, and not official information, for reference - just because somebody else posted something, doesn't make it so - very misleading - just as misleading as telling people you don't come here, when you have been a member since 2005, and continue to post copywritten material from this site elsewhere without permission (as if we were never going to do anything about it, though it is great advertising for us) i wasn't going to single anything or anyone out, but it seems unavoidable - either they refuse to grasp the following concept or are unable (perhaps they spent a lot of time on the short yellow bus? - hmmmm - maybe that's why they chose........) no offense jim
i digress - moving on
everything i can find from any official source says that TUV certification does not necessarily mean performance claims are certified - germany does require that any system sold in that country has a TUV certification - they have very strict quality control and acoustic standards - TUV certification insures that they meet those minimum standards - everything i can find from TUV says that they do indeed provide a performance claim verification service, but it is not automatically included in the basic certification - you have to pay extra for that - it is a separate certification - i have seen no such certification - i have seen no data to support the performance claims - neither has anyone else i can find - i am happy to retract this the moment somebody, anybody, proves otherwise
i do find it odd that in the shot on the cargraphic website they show an air filter in their package that won't fit in the 968
at no point am i slagging cargraphic or the system - it seems to be well made, is made of good material, and complies with the minimum emissions, acoustic, materials, and quality standards required - the company has a good reputation, and i have no issue with their products - it would be nice if they backed up any claims they made, though i can't find those either anymore - they have been retracted from any advertising i can find
i could buy any kind of exhaust - i could run any exhaust - we looked hard for ANY charts or any kind of data to support the cargraphic claims - none exists that we can find - the only data anybody could find showed losses in areas i did not want to lose anything - we've certainly spent enough in the process to have bought 10 cargraphic systems if they danged things worked right - everybody knows that i will swap out any component i have the minute something better comes along - i'm on my 11th system now, and it's not like anybody else's, so clearly i'm willing to change stuff out in search of the best performance - i don't care where things come from, or who sells them - i just want the most performance - if it isn't already out there, i'll design it myself - i'm running what i want for my own reasons - i've spent enough time an energy delineating my likes and dislikes of all of the other systems, including the rs barn
pete has been very careful not to make any claims of increased power, and in fact has only said that it doesn't lose power - to date he is the only one to do that - i respect that - other manufacturers make claims, but have never provided any charts to support those claims on a 968 - i've even seen somebody try to pass off 944 charts as 968 charts
something very important to many people about any claims or any system, is how they interact with other modifications - they don't all act the same - this is something to consider when choosing any system - this is something that pete has spent a lot of time and resource working with to insure that other modifications are optimized with his system, and that they don't complicate the end result
i personally don't care what anybody buys or uses - i don't currently have any interest in any systems, i don't make a dime on them, and never have (though i've sure spent enough in the search) - i only point out what we have learned from independent testing and development of other systems as well as ones we have worked out, featuring the good points and bad of all of them, in hopes that others don't get something that is less than what they wanted or expected - we only got into developing stuff because nothing out there worked perfectly - nothing
so, buy what you want - test what you want - run what you want - shop smart - look for data - talk to others who have stuff - compare performance data if that's important to you - compare materials or aesthetics if that's important to you - get the shiny tip or the black tip, the round one, or the oval one - do whatever you want - don't listen to any one individual, and think for yourself
