cat question

[B16Z6+S20]

if i remove the catalitic from mi 99 GSR and instal both sensors to a direct pipe in the same order, will i get a check engine? and also is there a way of removing the cat with out any complications?

there is a resistor clip thing that you have to get. The first 02 sensor won't care, but the second one will notice that there isn't a change in emissions so it will kick a code, which might make your car run like shit.


Why are you takin the cat of in the first place??

[B16Z6+S20]

i just want to make the flow faster, for more HP

[Schister66]

well unless you have other things done i.e. Intake, header, exhaust, cams........etc, it won't really do anything

get an o2 sim for the cel.

just keep the primary on the header and the secondary on the hi flo and you will be fine.

i still think its really pointless unless you're going to be doing some other work with the removal of the cat......but that's just my

all u need is an o2 simulator.

you are right
hondas 3 way cats flow awesome unless your going insane N/A *i've seen 225WHP N/A running cats fine* or turbo I see no reason to touch your cat.

If your cat is dead replace it with a smog legal and highflow like I have cheaper then honda and it "flows better" look into catco random tech etc.

man if i had know it sooner i would have save a few bucks, any ways i dont know if the one i installed is smoke legal cause theres no smoke restriction down here, but its supose to be beter than the original. and one thing i noticed is that the original cat has two scren inside, one on the begining and the other at the end, and that has to restric the flow a little. any way its already done so i gues il have to live with it. thanx to all for caring.

I know you said it is already done, but as Ace already said our cats are pretty efficient at doing what they do without losing power. I have a custom 2.5" straight pipe in place of my cat and the only difference is I can hear the VTEC engage more now than before. no real power increase. I felt a much bigger increase when I ditched my power steering and A/C.
