hey guys hows it going? does any one know where or who makes a high flow cat for a 06 Xb? I live live in so-cal. I looked on this site, and I dont see them here!

 

Check out Magnaflow.com they sell California spec high-flow cats.

You can also PM Stylis on here.. He owns Precision Muffler out in Cali... He is the man and can get you a high flow, that is where I got mine.

 

Thanks guys! I called I few places about high flow cats, and thier trying to tell me that they dont make them no more because the laws have changed in california, rather thats true or not! They told me some thing about the O2 sensors are different and the OBD. One sho ptold me I was better off going ith bigger tubing, which I dont have a problem with, but I dont want it to pop or sound like ____, so my question is how big should I go?
Should I contact Magnaflow and ask them is they sale some thing?

 

Changing out your exsiting size diameter piping (factory) will net you more top end WHP, but take away some low end torque.. I went with 2.25" from the header back and loved it.. I had a magnaflow muffler and tip, aftermarket resinator( not sure which kind it was) and the high flow cat.. If you plan on staying N/A dont go over 2.25", If you were going F/I.. 2.5" all the way.. it really makes a difference..

 

Yeah, talk to Magnaflow they make California standard high-flow Cats (Car-Sound is made by Magnaflow). The ODB will change but not for a while all you need to do is get a Cali-compliant cat and everything will be fine.

Also what ProshopXB stated above is true.

So send Magnaflow an e-mail or call them, whichever is your preference.
