to cat or not to cat
Hey guys,
Within the next month or two, i'm going to have to replace my catalytic - SHOT! but I'm debating now if i should just go with a cat-less mid-pipe.
Any one out there who has done it have anything to say? advantages? disadvantages?
Emissions will be an issue, but ha i just had them done a month ago so i got some time before i have to worry about a re-test :P
any feedback would be much appreciated.

Well.....looks like you answered the one major question - emissions.
If you have a lot of time before you have to re-test, I would get it. What are the advantages? You'll get more power - 8-10 hp gain. What are the disadvantages? Smell and the fact that your car will not be legal to drive on the street. You would possibly get tickets from police - I know in California you will for sure.

yeah i thought about the cops - unless they pull me over for noise, i don't know how they would know. Here in CT its not as bad as it is in CA im sure. I'm thinking it would kind of be dumb to have to redo the cat in two years on top of the cost to do the catless initially.
that being said I am worrying about noise laws. My roommate has a glass pack on his liberty, flow master exhaust, and he's been pulled over, despite being under the decibel limit.
I do like the additional horsepower though...I think i hae some more research to do - anyone have any idea on cost for the catless? Is it a big enough savings for now?

midpipes can run from 125(OBX non resonated....LOUD) to like 400 dollars...all depends on HOW loud you are willing to stand.....the more resonated the quieter it is.....but if you have to have emissions checked you WILL NOT pass without a cat....and I know a cat for the 8 is a shitton of money...(not sure exactly but I think over 1k bucks...dont' quote me on that though).....

yeah you're right about the cat - its some where around 1k to 1200. I'd definitely have to get some quieter ones, but then at that price, its probably worth just doing the cat, since i'll eventually have to do it anyway.

Your cat still has the emissions warranty. Go to mazda and they will replace it.

question???
alot of people on other boards for other cars ( YES, there are other cars out there) are hollowing out their cats to be used as a race pipe after the factory cat craps out. pro's - con's? is the factory pipe restrictive, smaller ID?

There's a DIY here on how to smash out half the catalytic material on the stock cat. That leaves it still functioning, but removes some of the restriction. DIY is pretty interesting because the material is pretty tough. IMHO, removing the cat for the sake of a few HP is irresponsible.
Schiraldi - glad you decided to stick with a cat. You live in Connecticut, whose civil servants are not above browsing fora like this to catch people who publicly confess to crimes.
The dealer offering up only an OEM replacement brings back a memory of when the cat in my daughter's Honda went. The dealer told me what the OEM cat would have cost, then said that was ridiculous and recommended an aftermarket one for less than half the price.

plus, i don't want to have to replace it again in a couple years for emissions. I'm a lot happier now that I don't have to spend 1700 at the damn thieving dealer. I rarely let them do anything on any car for that reason.
thanks for your help guys.
