Message	problems with the oil seals on their turbos after installing downpipes. Jim Wolf claimed it was a result of the lack of backpressure that the stock exhaust provided. Ultimately, it seems that this problem primarily affected owners who had their turbos in the car for an extended period of time with the stock precats and cats. Apparently, if a turbo is broken in with the stock exhaust parts it gets used to the backpressure. When this backpressure is reduced(as with downpipes), the seals let loose.
