Hi Flow Cats
Anybody using Hi-Flow cats on their cars? I know theres not much of a performance gain if any but I hear it really makes the car sound nasty...Especially if you have an aftermarket cat back on. I dont want to go with headers at the time so a few suggested the cats with bullets if you really want to WAKE UP THE BLOCK! LOL...
Anybody got em? If so how much do they run? Will it pass NYC emissions? Do they sound good? What make/model do you suggest?
Any information is be much appreciated! Happy New year to all...

im not aware of any high flow cats that bolt on to the factory manifolds. the performance gain would definitly not be noticeable so long as your stock cats are in good working order. save your money for set of long tube headers and you will be much happier with the results!
