Question MRT header/high flow cat

I have my mind set on buying a set of MRTs tuned length headers and high flow cat combo but have one concern about emisions. Not worried about CEL since I am OBD 1. Will a high flow cat burn off enough CO to pass or will I have to be swapping exhausts like crazy just to be "legal"?? What a bummer it would be if these aftermarket companies made things that would keep a vehicle from being legal...

It should, in fact, i believe that even most cars with high flow cats and if properly tuned motors will pass in even California.

It all depends on what type of cat is used. The stock system has two cats, each does a different job. I honestly don't know what type of cat is in the MRT but if i were to make an exhaust i'd put the one that matters the most to pass emissions. But thats me.

I've passed the MA emissions testing, I know people have passed the CT testing, how strict is CO's testing?

I also passed in Massachusetts! So you should'nt have a problem. Is this for a 2.2 or 2.5? Good Luck, Keith

AFAIK, CT's standards are (or were, before they reorganized things a year or so ago) very close to if not the same as CA's standards. Since everyone knows CA is the Smog Nazi Capitol of the World, if the MRT setup passes there you should be good to go anywhere.

I have the header/cat combo on my car, but moved to HI before I ever had to get the car emissions inspected in CT again.

Hey, thanks for all your input, guys...LOL Keith, I am putting these on my 1.8
It's a little monster already with short ram intake, pulley set, grounding mod and a few key suspension bits. I don't know what it is but it's got enough top end to keep up with nearly anything stock and suprise any of those ricers with 15 grand under the hood of their POS civics.. With a free flowing system all the way back, my mid-range will be devastating too so I don't care what happens to the bottom end cause it's pretty tourqey already
This perfectly describes the look on people's faces when I say: "It's only a 1.8, man"

BTW- CO is not very strict w/ emisions. My car only has ONE cat and ONE O2 sensonr anyway, since it is OBD 1 and Subaru didn't change this until '97, I believe. Also the stock piping on these first few years is only 1.8" which is 1.5" inner diameter!!!!

Wow, 1.8, well there a lot lighter than most. I know what you mean by suprising a few cars. I have no problem suprising WRX's, RSX, Spec V and the like. The first two/three gears in the RS are real strong!! Good Luck, Keith

First, let me call the BS on that one.

Second, are you sure the 1.8 is dual port??

Phil =)
