I own a '08 Altima with a 2.5 and so far no problems and we have about 26,000 on it.
Two friends own SpecVs. One has a '02 with over 120k on it and he installed a header at 110k. So far no problems. I am actually purchasing this car in the next week or so. Another owns a '03 or '04 and he had under 60k on it and had engine problems due to the precat. Lucky for him he got Nissan to repalce the engine but it wasn't easy. I think he had to bring it to like three different dealers to get it done.

IIRC this was resolved proior to 2006, but still worth looking into.
