| I can't go and give hard scientific proof no easier than you can without taking samples and going through the scientific method with all of it. A near impossibility in 15-year old car enthusiast world. However, what I can say is look at the sheer number of cars with open exhaust. Go back to your days at Z1 and I'll recount when I used to hang out at SpecialtyZ. Even if we just took that sample...the thousand or so cars that came in, 90% of which had DPs/TPs. Out of all of those cars, how many have severly smoking turbos? Now out of those, take out the ones that were smoking from install issues, user stupidity, etc. Quite a small sample, isn't it? Factor in the thousands of cars on this site with them...from all different countries. Nothing even remotely visible in the complaint department whatsoever. How about all the various tuners in Europe and Japan that do these things to all sorts of cars? Sometimes using the very same brands (JWT/HKS/Greddy) of the turbos we are talking about. How come there isn't some huge outcry from all of these people about backpressure concerns? Instead, you have a few cases over the course of YEARS where people have had new turbos and have had problems. I can completely understand the turbos being scrutinized at that point, but not the exhaust that a few thousand times as many people own and have zero problems with. Sure, open exhaust may cause issues on turbos that already have a tolerance issue but to stand here and make sweeping generalizations just shows you either aren't as smart as you think or you have other motives. It couldn't be that you have a product you've done to your own car to battle this somewhat, could it? Guess we'll never know for sure. The sky isn't falling.
