Hey guys, my cat's been rattling lately. I took a look under-neath my car and noticed the car has 2 Catalytic converter's. I was wondering if its possible to replace both Catalytic converter's with one? and if there are any after market cheap solutions out there? I want to know what you guys recommend, i want some what of a proper job done, but i'm not thrilled about spending big money on my car either.... let me know guys!

thanks
