I'm looking around for High Flow cats because im getting my downpipe rebuilt. I just wanted to hear some opinions on what is the best or "highest flow" Catalytic converter available. My number one choice so far is of course the magnaflow high flow cat. and no im not picky on the price

Thanks

I ran Magnaflow cats on a heads/cam LS1 with long tube headers/AFR205s/ TSP233/239 cam, LS6 intake on 91 octane and made 439rwhp with them. They only suck up a few HP..... and make your car way less stinky.
