If it's worth getting, where is a good place to get one and how much? TIA.

I can potentially wait, depends on how long. But what is price, and any idea on performance?

Default ok, well i'd like to hear about it when it's available..
..but i can't really decide whether to wait or not without at least some ballpark info on price and some advice on the performance increase of a typical hi-flow cat. if you wanna email me with some info on the DL, that's good too. thanks.

Default hi flow cats on the a4 are a 50/50 shot for CEL's...
each MY and car seems to be different....

the proper one that seems to be good is the one Charlie has, which is the EVO renkatt.. but its 600...
