Catalytic Converter Question.
 

I was looking around the forums yesterday just browsing for things that caught my interest and I came across a post about an exhaust question. I saw within the answer of that question that all 2000 Tibbies have 2 catalytic converters. I was under the impression that only the California bound Tibs had the 2 cats. Anyway after I got done reading all of the replies to the post I went outside and took a look for myself... you think I would have saw this before. Low and behold I saw the second cat right under the exhaust manifold. I know I saw that piece before, I didnt think nothing of it and thought it was just a heat shield. :confused: hehe guess I was wrong.

Here is my question...
Being that I live in PA is it safe to remove one of the cats and the resonator and still pass my emissions test? Keep in mind I am running an Arospeed BOMB muffler. If the answer is yes... what cat should I remove?

For now... I just want my tibbie to sound as loud as possible without taking the next step in a complete exhaust setup. The Arospeed BOMB muffler has a nice deep tone that I really like... not a ricey sound at all. But I feel that it should be louder tongue.gif
Somewhere down the line I will be doing a complete Exhaust setup, but as of now Im just looking for "cheap" loud sound. :D hehe

Thanks guys,

NEWS FLASH.. .RED WAS RIGHT...

i always thought my elantra had two cats.. because half way down the ehxaust pipe there is a big round "cat" looking thing.. but today, i went to the muffler shop, had them chop off the stock cat-back.. and SURE ENOUGH ITS JUST A F*CKING RESONATOR !!!!!!!!!!!!!!!!!!!

my car only has 1 cat !!!! .. the one up by the headers...

anyhow, i have a custom made 2 1/4 inch catback with regular crush bends and a standard "turbo" muffler.. i paid $200 for everything..

now watch me go 14.5 at over 95 mph !!!!!!!!!!!

ford you didnt answer my question, but thanks for your uhhhhhhhhh info. tongue.gif

oops.

just remove the middle resonator (trust me, its not a cat)... your car only has 1 cat.. just like mine..

i THOUGHT it had two. but that big thing in the middle is just ANOTHER resonator..

my car had a total of 3 resonators!!!

now they are all gone ! and i spanked me some rice on the way home tonight !!!

took out a civic SI, with headers/catback/intake and suspension work... he also had a stage two racing clutch... i came out of the hole sloow... he got just a notch in front of me then i sprayed,, my nose came up hard as i spun the tires and then i hooked, put 5 cars on him by 60mph and i shut off... repeated it again.. and i beat him by 5 cars @ 60mph again!>... then i raced him on motor, and he put 5 cars on me by 60mph .

sad.gif

damn my car is slow without the juice.

so your saying to remove everything after the cat on the exhaust manifold? if thats whare you saying i will be cutting out two more units... one looks like another cat (you insist that its a resonator tongue.gif ), and the other is a resonator for sure (looks like a cherry bomb).
ill have the sound now im sure, but how about my emissions?

Thanks,
Börg

emissions are not affected by resonators dude.

smile.gif thats just a sound control device.

Dude, I have a '99 Elantra and removed 2 out of 3 res. If you remove cat and res. there is no way you are gonna pass emissions, you'll be just like me!!!!! :D :D :D :D

Has anyone tried one of these hi-flow cats, if so could you recommend one?? The situation is...we didn't hollow out the cat when we did the race header (boot-leggin'). And now it is melting, so I think I might go with a hi-flow one. Any recommendations would be helpful. thanks!!!
