Hey guys I am asking if there is a difference between my Cali catalytic converter and the 49 state/high flow cats? Obviously the price is one thing and the material used, but is there a difference in flow rates/power gained if any at all between two? I only ask this because I am thinking about buying a high flow cat, and was wondering where to buy one like a Magnaflow or any other brand out there. A lot of places wont sell to me since I do live in California, makes sense they are watching their ***. Thanks guys if you do reply to this thread! Its much appreciated.

 

if it's street driven and you need to pass smog you can only install the cal cat

 

trust me I totally understand that and yes my car is street driven, but I would like to install a high flow cat or the 49 state legal one I just need to find a vendor that is willing to play ball. I am wondering would all the fuss even be worth it to get this type of cat delivered to me here in Cali?

 

If you have a 5th gen, get the magnaflow 446604. It is a CA exempt (approved) high flow cat. I paid $322 for mine at Rock Auto (everyone else online wanted $395).

 

I do have a 5th gen and I did buy the Magnaflow 446604 Cali cat,and yes they were crazy expensive I paid $280 for mine. I didn't think it was a high flow cat, but I will have to do a bit more research into it.
