High Flow Cat on A Honda?

[Weapon_R]

I've heard conflicting claims that these either

a) Do wonders for performance gains

b) Don't do anything at all

Is there anyone who has installed a high flow cat and can comment on this?

doesn't do much for performance.

every situation is different. what kinda car, what kinda mods u have already...etc.

It won't help you much. The stock cat is actually pretty darn good. The only time I would even think to get one is if you are getting a fairly large diameter aftermarket header/exhaust combo. And the only reason I say that is because it's kinda gay to go from a 2.25" collector to a 1.75" cat to a 2.25" exhaust. Plus, I'm assuming that if you have a large diameter exhaust you have the engine mods to push the extra fumes.

Go with a test pipe if you don't mind the noise

And if you DO mind the noise, get a turbo!

Boost is your friend

Big improvement w/ a turbo, not too bad w/ non and helps the exhaust system last longer...

hey I was wondering, is it still consideribly loud if I have just a test pipe, but with a turbo, or is it all the same and the car isnt that loud at all
