i have a 96 and i want to get rid of cats and run o2 sims what are the pros or cons i know this has been beat to death but your oppinion is appreciated thanks

 

It depends, the main difference is the sound, this is a pro for some people and a con for some.

 

what about power ???? will i feel it

 

I don't think you will. When I put dual cats back into my mufflex y-pipe, I didn't feel a difference. I will soon dyno it to find it how much I "lost". These were high flow cats though.

Busting the cats just makes it more difficult to pass emmissions and the car will stink.

dont do it, cats are there for a reason and your car will sound like *** if you do gut them...

 

you gotta look at it like this, a catalitic converter is some sort of a crude exhaust filter if you will...and as the same as an air filter, one day its gonna stop up....if you ahve a new car or a low mile car you probly wont get much power...but i gutted mine when i had about 70K miles and i could feel it...above 3500rpm or so it felt stronger and ran about 1-2mph faster traps...someone else may tell you different but thats MY experience...i would do it and as for the sound its a bit raspy'r but hell that car wasent made for your grandma...anyways it wants to be raspy and so do you...lol

and another thought you might consider...do NHRA top fuel cars have catalitic converters??? hmmm you tell me...do it bro you wont be dissapointed

 

are nhra top fuel cars driven on the street?? UM NO!!!!

 

Are the SLP shorties 1 5/8? I think so. If that is true and I don't see a cat back system or aftermarket Y pipe... My hunch is it will be louder, maybe, maybe a very little bit more top speed, but not much else. The stock cats flow pretty well on these cars.

Now if you had long tubes and 4 1/2 inches of cat back I would have a different opinion.

 

i think gutting the cat will probably make it sound like crap or raspy put if you just put a straight pipe there instead of cat i think it sounds alot better and not raspy. if u gut the cat a lot of hollow space there unlike a straight pipe. tell me if im stupid or wrong cause i haven't tried it on my car yet hehe.

 

They're 1 3/4.
Headers, no cats and cutout will be very loud and raspy IMO. But some people like that.

 

No. Minimal to no power gain, sounds bad, smells bad, pollutes. Sounds like a loser to me.

I gutted mine... I like the sounds and who gives a **** about polluting. Its louder and more sharp sounding, as far as power I dunno but I like that smell

 

LMAO!!!!!!!

I did about 2 years ago and it's like, hmm, what did I gain? I gained big *** clouds of smoke at WOT, I'll tell ya that much. Been a while but I think I gained 2mph and lost .2 or lost 2 mph and gained .2.

 

would gutting the cat and putting an offroad pipe there sound the same or not? i wanna know before i purchase my whole exhaust.

 

i love my ORP....when i took emmisions and had the cat back on....i couldnt wait to put it back on....stupid cat sounded like s***! ORP all the way baby!
