I haven't any recent time. To most people its fun to fit in with the people that have issues, the stainless steel being the main reason ( which they have began to remedy with t-409 ) and just like with ricers, no chambers and baffles add 20 horsepower

 

then wouldnt you want straights i miss my straights

 

So its been a few weeks or so and 2 tanks of fuel. no codes or anything, im still waiting for them to come on but i have been lucky. One question tho, the o2 censors right after the front cats is that what controlls the air fuel mixture?

 

The front sensors control air fuel, the back sensors check for working cats.

 

Okay thats what i was thinking. so i shouldnt have to worrie about runnig lean/rich?

thanks

 

if you cut all 4 cats out like i have. just get mil eliminators for the back o2 sensors. easy as that, no codes

 

okay thanks for the help.

 

Weird

 

Yeah I will, but after I get my X pipe and duel super 44s.

Yeah..... I forgot that, my bad

 

Eventualy you will see a check engine light for cat efficinecy, wich will cause you to not pass emissions, if you have too. Ricers use an extension pipe that offsets the second o2 sensors from the pipe. That usualy fools the sensor for a good long time, but it will still occasionaly throw up the code.

Something like "bank 1 sensor 2 reporting out of range."

I can't figure out why everyone is saying you can't remove all the cats or your truck will run like crap. Cats don't due anything besides creat back preassure, so long as the pipe is not too big, it should be fine.

 

So the other day i used the edge and tuned the truck back to stock to see if anything came up, and nothing came up. i tuned it to lvl 2 and still no codes so some how its not trowing a code.

 

Maybe he put those O2 sims on the ends of your O2s to kill the light, or, is there fresh welds around your front cats? Possibilty he never even touched them.

 

I wonder. thier is fresh welds cause its going back in to get the leaks fixed tomorow. ill find out for sure about the sims tomorow if he did put them.

 

so i got my first code. i didnt really look at it to close haha it just said something about the catylist converter so i just deleted it quick, it hasnt came back on since. i tryed to put my CAI back on and my truck ran like crap and i got lean codes. i had it one before i had the cats done and had no problems. i guess i gotta get some custom tunes from php.

 

Ok well u guys will probably get a good laugh on this one but what exactly is everyone talking about "rear cats". I havent really spent alot of time under there but all I did see was the 2 front and a tube with clamps that honestly looked like a botched diy job then the ginourmous muffler that i had cut off at the muffler shop. If anyone has pics of the "rear cats" that would be sweet
