How much do you think the perf. ex. added? I was thinking about leaving the stock exhaust and just installing the PPK.

The exhaust probably has minimal gains. ~5hp at most I'd say.

I really appreciate all of the links, info, and discussion..... thinking of buying this online and having a local dealer install it, after doing all the reading it seems like the added oil cooler warranty-free worries and decent performance numbers make this an intriguing choice.

Note that the PPK adds an additional water cooler (connects to the radiator). You should already have an oil cooler.

Yes, it only adds an additional water cooler. Personally they should have added a secondary oil cooler similar to the stock one. An intercooler upgrade from them would have made some sense too. I do have this kit and initially I was very impressed, but for the money plus labor you kind of feel ripped off. On the dyno with BMW Performance Exhaust I made 287 whp and 343 wtq, not bad for 70+ ambient temps. Unfortunately I didn't have a stock dyno performed before the install. Also 92 is the highest octane gas you can get here unless you can afford to run race gas.
