Hi-flow cat, good or bad?
I know the car hasn't come out yet, but do you guys think that a hi-flow cat would benifit HP if it's ran with a cold air intake and TRD exhaust? and eventually with the supercharger. That's what I'm thinking of doing, but I heard something about back pressure and loosing low end tourque or something like that, can anybody further clarify this for me. Thanks.

are you asking about a high flow for the TC?? If so, there will never be one available, the TC has whats called a thermal reactor converter which is molded to the exhaust manifold. Toyota really scred this one up, the TC cannot have a header or a high flow cat design because of this. I have already been in the works for the tC exhaust system for some time.

a highflow cat is virtually useless on a car that isnt forced induction...even more so a car that isnt turbo. I would save my change and get a FI kit for the car first, then worry about the car. Out of the box on a stock car...a high flow cat will probaby give you 2 hp, and take 5 ft-lbs away.
High flow cat is like 300 bucks in some places...spend 500 and put a bottle in the damn thing.

stop bickering. I bet neither of you haven't even changed out your injectors were a few of us, including myself, have.
my car has 12k miles on it and it hasn't been legal for about 6k of them...who cares...check engine light hasn't been off in months
stylis, let this man know my exhaust system

My scion has 300 miles on it, so no, I havent touched the injectors on it. Not that I think that thats a big task, Ive done it one my DSMs and other cars in the past.
