Best High Flow Cat option?
Send your stock cat to WORKS--they put 3" piping on it to increase flow and you get to keep your emissions equip in tact and not thow a cel as a result.. I did it and no probs, flow is noticably better without all the issues.

Thanks Bink. It will be interesting to see for you and others that use larger CAT's but still OEM internals will or will not pass emissions. I had to go "under the table" to get my old DSM to pass probably due to 272 HKS cams. I do not want to go through that again so it would be nice to get a less restrictive CAT but still pass emmisions.

Usually for cars that are OBDII they just hook a computer up to the ECU and do a visual CAT check. I don't see any reason as to why the COBB wouldn't pass a visual check. I haven't gone through emissions since I had done my cams, but since (at least in CT) they don't put anything in the tail pipe, I'm pretty confident it will pass.

Hey Ken-
I have an Apexi 3" turbo back exhaust. I was using the stock cat with Apexi downpipe / catback for a while. Once I put the COBB high flow cat on, there was a noticeable difference in how the exhaust sounded as well as noticing that the car pulled harder up to red line with the new cat.
I choose the COBB cat for a few reasons. First, it IMO it looks the best out of other companies cats (no weird heat shields / huge catalyst housing). Second, the catalyst itself only takes up a small portion of the pipe and the pipe itself is actually bigger where the catalyst is located.
If you are asking whether I had the car dyno'ed before or after, or if I ran it down the strip to compare, I did not do that. But I can say it mellowed out the sound of the exahust, I don't get a CEL and haven't had any issues.
