ok so i wanna take off my cat cuz well who doesnt want the truck to sound a little better but i wanna know what kind of o2 sensor is on my truck, where is it(front or back or both) and how many?

i got a 2003 dodge dakota 4x4 ext cab or club what ever you wanna call it, k&n cold air, throttle body spacer, superchips comp, cat back 3" exhaust with dynomax muffler, stereo with 12" sub which i only put in cuz i was installing a deck so why not show a ricer how the trucks do

thank you

 

First of all what motor do you have.

Secondly, you have 3 cats:2 pre cats and a finally cat. They each have 2 o2 sensors, one before and one after. And what state do you live? Some states you can not get away with it, like CT where I live

 

4.7 and alberta canada

 

and manual tranny if that makes a difference

 

nice you have the same truck as i do.

What do they do as far as inspections/emissions up there?

 

what testing? lol no its not bad ya its a ticket but they dont need to inspect till it hits 25 years old i believe but not if you dont get caught

 

delete the pre cats and keep the single cat before the muffler, and use sims for the rear o2s.

it should be loud with a new muffler like a spintech race or borla single chamber muffler dumped under the rear axle.

That should be fine.

and ditch the Throttle body spacer.. unless you plan on using it as a n2o injection plate... otherwise its useless.

 

Jeez you guys can get away with murder. Here in CT you get screwed. Can't have the CEL on, have to have all the cats, and they plug it in and get all the readings, if any are to high or low it won't pass. Its a b!tch

 

lol i used to have an 83 cutlass from my dad and when i got it i just took it to my mechanic he passed off on it and that was it it was never tested lol just that one time of 25 years of us owning it. What is CT i dont know all abbreveations.

Ya imma just keep the throttle spacer on i know it doesnt do anything but it sounds like its supercharged lol and i payed for it and i hate wasting money lol.

i love my dynomax muffler it sounds good that will stay on for sure,

 

CT = connecticut

i am all for getting a good sound an all but you might lose some mileage by having fewer cats (less backpressure = computers go ape****) but if you still have the one than you should be alright.
