i have an 01 trans am ws6. im pretty sure my stock cats are plugged pretty bad. my engine knocks and the dealer agrees that it might be the cats. id like to know what brand would be the best to get performance wise and also price wise. im kinda on a tight budget with this thing, but i want the car to be a fast daily driver. i live in california and there are tight restrictions, but i still want one thats gonna perform better than stock. can anyone help me out here? or lead me in the right direction?

GM covers the cats to 100k I think have them replace them with stockers...

other than that, magnaflow makes metallic spun cats

Ah thats the best part about NOT living in California....not having to worry about emissions, which is why I'm able to run true duals without cats as soon as i can fork up a couple hundred dollars

I just put a custom-Y with hi-flow Magnaflow cats and have no complaints at all.

You can do that here too if you cough up a few hundred every time you need a smog check.

I have a Magnaflow cat in my '85 TA, and yes they're CA legal.
