cracked UrQ EM

[RndLiteBMW at aol.com]

My UrQ is now making the classic Audi 5 cylinder cracked manifold "chuff 
chuff chuff." I noticed a slight ticking on startup on Saturday, and began to 
worry- then I autocrossed it yesterday.  Now it sounds like old truck.  I''ve 
forgotten-is the manifold an UrQ-only part? My questions are these:  Can I 
still get a new manifold (Audi or aftermarket)?  Are there good (better 
flowing?) aftermarket alternatives?  I know about the Dialynx manifolds' 
tendency to crack, so that's out.  Just wanted to see what the collective 
wisdom of the list thinks before I proceed :)  Thanks for any help/advice!

ps:  Has anyone fitted the 2B Quickrev downpipe to their cars?  Any comments?
