I ended up having to go back in and replace the pipes on mine. I even polished up the ends a little when I did the WP and valley pan, but it started leaking when the weather cooled off - guess they were slightly pitted or outbof round.

If you shop around and find places like BMW of Morristown, there isn't even much price difference between discount BMW (20-30% below list) and aftermarket. If you are unlucky to have a local dealer that charges 20-30% over list price, like around me, then the aftermarket stuff seems way cheaper.
