people say not to reset the ecu. i read that the ecu is constantly learning and making adjustments to the car. so if it is "learning" how long before i feel the full effects of putting a hi-flow catalytic converter?

 

uhhh.....a hi-flow cat isnt going to pin you into your seat when you step on the peddle..
Its just a free flowing exhaust.
Take two straws.
One from McDonalds and one from Burger King.

McDonalds = stock cat
B.K Hi Flow.

blow air through them both and you'll notice the Burger king ones flow better cause its a bit bigger and less stuff in it to restrict air flow.
Just know your car exhaust will smell becuase of that.

 

Ahhhhh i suddenly understand now
speaking of pinning myself into my seat. how can i do that w/o a turbo, supercharger, or NOS????

 

GO full n/a build. Or an h22a

 

Yeah and be careful letting to much airflow through cause no backpressure is almost as bad a stock exhaust

 

Nitrous Oxide or the company NOS?

 

and that still won't do much for any power gains.

basically if his set up was stock intake, stock header, hi-flow cat, and stock exhaust...it would be

McD straw, McD Straw, BK straw, McD straw

you're getting the same amount of air flowing in and out....sooo no difference.

 

unichip made an ecu for the 6gen accord v6 and i think 4banger as well that will replace the whole ecu unit..

 

nah got an aem cai intake, hi-flow cat, hi-flow muffler so now what?
