Its a high flowing exhaust piece that replaces the stock CAT. It removes some of the emmissions but not enough to allow the PCM to think its working and so users normally have to add some sort of 02 spoofer that will tell the PCM all is well.
i got mine from SLP for 180.

I'm not sure I would get the hi-flo cat without headers, or ported manifolds. Your stock cat may flow better than the stock manifolds so your bottleneck would be the manifolds not the cat. Once you open the engine up with headers then the cat becomes the bottleneck and hence the need for the hi-flo cat. MO though, I could be wrong.

We have a high flow cat on the GTP (and have for a year and a half) and it has NEVER set a code. It has no spoof or anything. The 02 sensor is plugged right into the exhaust after it, and so far no problems.
I know that now we won't ever have any problems with it because we got the code removed from the PCM so we can take the exhaust off at the track, but that was just a few weeks ago. It was fine for a year and a half before that. But I know some people do have problems getting an SES light.
