members who have downpipe and stock CBE that I can think of off the top of my head:
Mr Wilson - soon I'll convince him to buy a CBE
Horto - although he's already bought a CBE just not installed yet
Breakfasteatre
Fywdyl
MBNTO - unless you changed it for some "Bling Blang"

Celestespeed3 - yours is stock no? I know everything else on your car is cp-e
anyway and I'm sure there's a bunch of others as well, so it's more than possible to connect an aftermarket dp to the stock CBE.
Anyway I've got plenty of time to convince you not to spend all that cash on the cobb and buy something else. As you read more and talk to others on this forum, I'm sure you'll eventually convince yourself to go with something more reasonably priced.
edit: Cobb AP and fuel pump internals are not "little things" that's still about $1000 right there.
edit2: just saw Fobio's post - hahaha
