is it ok to run no cat?

If he only would gut the cat,instead of putting in a straight pipe, then there would be something to really talk about. Look out Vipers!

yea specter i am! And i ran the pipe today, it sounds way better and louder, which was what i was going for. No power increase, which i expected, but one of the joints leaks so it gives a really whistly raspy sound, but ill weld it all together sometime next week and it should take care of it. But thanks for all the info guys!
is it actually running rich now, do i need to tune it now? With my upgrades so far, after i port and polish my throttlle body, would it be worth the money to get the pcm flashed for my upgrades? How much is average to get that done and where?
ya dude that can deffinetly sound bad ***, but there is also things in regards to health with no cats and wiping out the emissions, the is such thing call nox gas, if your exhaust goes through your cats and its when your combustion chambers reach over 2500 degrees it creates that gas, its not that great to ingest cuz even if you ingest just one small gasp of it it stays with you forever and builds up in you tissues and there is no way to get rid of it, and once it builds up enough it attacks your liver and then moves to all of your other arteries, i know i might sound like some stupid guy that doesn't know what hes talking about, but this is true stuff and i'm sure that most of everyone on this forum agrees with me, cats to some people may be useless but if you have a exhaust leak in your car and you don't even know about it, it'll kill you in no time, its odorless, tasteless, and you obviously can't see it, plus if you get caught taking them off, that could be like a fine of 10k and 5 years in federal prison,in my opinion it would be worth it to keep itin, i know that my opinion probably doesn'tmean much but it might help you or someone else in the long run.
yea well that's all vbery usefull, i will get that leak i have in that once joint taken care of immediately, but the cat is allready off so not turning back now! Nobody will ever even know
and if they do, ill say i bought it like that!

anyway, about the pcm tune. Can i get noticable difference in power and gas mileage with a pcm tune for my upgrades? after i port the throttle body, hopefully this week.
possibly a defference, it might not be much but you might feel a little get up more than what it was bofore, if i were you, honestly, i would build up a 350 to throw in it, theres not a whole lot to do to v6's i had one in my 81 and after i realized that there was nothing that i could put into it, it was a 4 barrel carb, i just ripped that out and built a 355 small block for it, even a 305 would do it, i've seen 305's pull off some amazing numbers at the track, but i'd just rather have a 350, its always a good idea man.
thanks, i've heard that atleast 20 times, thought about it atleast 100, but that a **** ton of work and i'm not looking for big power. Just looking for quick, easy, cheap things to do because i'm getting ready to sell my car. The bigger the list of mods, the more impressive. I know some hardcore car guy won't buy my car, but it would be a good fun car for a new driver. learn how to drive a decently fast car that out handles pretty much anything in xchool, and then upgrade to something faster! So... no pcm flash. gotcha
