Cat replacing pointless?

[Chuki_breath]

hmm i think thats why you would of needed a new one. The cat should not look like that, my stock cat you could not see through. My aftermarket cat you could not see through either. My aftermarket one is made by Random Technology. Now people have been known to drill out all the shit in there stock cats to "free" up the air flow. We did this to my boys eclipse just for shits. Couldnt notice anything though......prolly cuz its a piece beater but.....

its stock dude im telling you, there is no drill marks or scratches on the inside that would implicate anyone messing eith the inside of the cat... and like i said before... this car is bone stock... the ONLY owner of this car was an old dude!!! he didnt even know how to change oil or anything period on this car... he would just always take it to a dealer for it to be done... an old fart is not gonna drill out the cat because he wants that extra couple hp hahaha... and then leave the entire car stock completely...

look at the front wheels of my car... thats how it was all around when i got it.. yes gay!! i almost want to go see a cat at a dealer to see what they sell and what it looks like..

Nah, I'm not ganna paint rims, I got no rims to paint, but if I get some and they need painting, I'll have an idea about how to do them. Looks like yours came out pretty good.

My cat was hollow too. I replaced the header and the cat-back exhaust. My mechanic said my cat was completely hollow. I think GT500916 is right dude.

ok here is what i think i know... the cat is hollow, i know this because when i replaced my cat with a cat pipe i saw this and i thought, then whats the points of replacing these? then i know of other people who also had hollowed out cats stock... then the post above me had a hollow cat so obviously im not hte only one....

but... the other day i replaced my header and believe it or not, but the cat is actually right after the header not under the car but right on the section where the pipe is going down from the header and right before it evens out horizontally.

I had to take that section off to replace it with my long header , and its not hollow at all there is stuff inside that would block air like a cat would. So the thing is when you do replace the cat pipe and a cop says something about it and is about to write you a ticket, you tell him and say... "you freaken noob thats not the cat i replaced, my cat is over thuure!! "

so you can replace that wanna be cat at the bottom of your car with a test pipe and you wont have probs with passing smog because your cat is actually else where... this is why guys told me before htey replaced the cat and passed smog, i now know why...

There were a few 240sx that had cats, and hollow cats. Usually a VIN number can distinguish the changes, kinda like trims. My S14 and many others iv worked on had honey comb cats. Other S14s and S13s iv also worked on had factory hollow cats. But the point remains, weather your car has one or doesnt have a cat..it will make no difference off the bat.
