I got my RX smogged a few months ago, it failed the first time, and they did some carb tuning and then it passed, but barely. What I was wondering is, If i put a new intake, an exhaust with free flowing cat, and a new carb, would I fail smog horribly?

Is there anything I can do to reduce emissions?
What about ATF?

Thanks

 

if you almost fail with everythinng stock imagen with all the thing that you want to do.

 

Eddie, that's my point.

 

you know it's hard to choose, performance VS ca.
i totaly understand what is going through your head.
and it's hard to say that with those mods.you will pass
so all i have done to my 7 is a hi-flow cat. keep in mind
that changing parts at smog time sucks,,,i'm just about
readdy to buy and install a 13bt.i'm not going to under take the project untill i'm certain that i've got the smog
problem taken care of

 

There was a discussion on high-flow cats awhile ago, i think the only one that registered significantly higher emissions-wise was the N-Tech cat. Intake shouldn't hurt emissions at all as far as I know. With respect to the carb, did you mean new stock carb, or a bigger one? If the carb is bigger, i'd imagine that HC would probably go up a bit-- it seems that the bigger carbs are harder to keep in tune sometimes.
