2 weeks ago i cut my back 2 cats off and yesterday my SES light came on. i have a terrible leak on the left side, if i sealed that up could that get rid of the light?

 

depends, what are the codes?

 

i dont have a clue. how would i figure that out

 

get'em read. autozone does it for free.

 

well what code would mean i could fix it by closing the gaps? whats the code mean

 

i had my cats replaced, the SES light kept comming on, so i did the GOTTS 02 MOD, its in my photo album if you wanna take a shot at that,

fixed my light for about 8 months or so now

 

no clue on the codes, but with a leak especially way up near that area your losing a little performance and gas mileage. Have a shop weld it up.

 

noone will touch it now that the cats are gone. ive tried. im thinkin of just gettin a set of 94106 cats on there #1 so the light will be gone and #2 the sound it has now is awesome, but it can get a little too high pitched and ''poppy'' when i really get on it and i dont care for that at all and those cats should calm it down just right. and #3 itl be legal (not that i care) but itl passs visual inspection

 

Well you do state good points, if you go that route hope it all goes smoothly. If you show up to a shop with no cats and have cats to be installed they cannot deny your service.

 

if its got lean codes then that can be caused by the exhaust leaks if rich or catalyst efficiency codes then its because of no cats.

 

would takin those rear 2 cats off make it run lean? seems like it'd just flow a ton better

 

yea i just dont like the idea of spendin about $200 out the door for highflows installed when ive got the 2 stockers at home that could go back on. Hhmm, extra sound for $200, or less sound for the price of my cats re-installed. decisions decisions.

 

with the cats removed the o2's may read rich and cause the pcm to lean out the mixture. with the exhaust leak they may read lean and try to richen the mixture.

 

you know you can get 2 high flows and just sell your old cats right?

 

Save up the $200. The more aftermarket high quality parts in your exhaust the better, dont put OEM cats back in it.
