I have a B&B tri-flo and recently lost one of the tips. I emailed them to try and get a new one but they wont sell them individualy. They want me to take it off my car and send it down to them for replacement. Do you guys know of a good on-line source for exhaust tips? They are 3" with a slight angle on them (15 degrees or so)

I'm not familar with the B&B tri-flo, but how similar is it to stock? If its close, you could get the factory chrome exhaust tip from any dealer, Part # 82119401504, it looks like this:

In fact, Pacific BMW has the chrome on sale for $15.60each ; black for $19.80 each:
