    Im looking into changing my stock cat on my exhaust to a more free flowing cat(performance) and was woundering if it would effect my emissions at all? I have dual 2.5" exhaust from the muffler back and 3" from the Y through the cat into the muffler

    Nope. I got a Magnaflow Hi-Flow cat right before I had to smog last year and didn't affect emissions at all.

    I've got 2.5" Walker/Dynomax stainless steel jobbies. They cost me $129 ea. from summit a year ago.

    I'm pretty sure this is the worlds most high performance cat:

    I have 2 highflow cats. Catco I believe. I am running true dual 2 1/4" pipes with highclow cat. I pass emissions in Phoenix AZ which is one of the hardest places to pass. There very tough with there laws. I pass easy though. Just make sure you heat them up well before you go to emissions. I ran about 10 miles of highway at 3000+ RPM prior and right before my turn in the bay I held the motor at 3500+ RPM to make sure they were plenty hot.

    How long have you had your Catco Hossbaby?

    I had one installed maybe two years ago...it had to get inspected twice since then, the last time it took a lot to get it to pass. I had to repalce a few parts like the IAC, which helped get it a little closer, change the oil, and work on the ESC crap. Even then it just barely did...i looked at my old inspection sheets and the HC's and stuff got a lot worse...maybe its because the engine is getting tired, but i also heard that aftermarket cats are only good for a few years.
