So got my turbo xs exhaust a few day ago and went to test fit it and relaized that my factory exhaust doesnt have a flange directly after the cat.... Is this weird? the cars completely stock and it doesnt look like anything significant has been done to the exhaust ever... i know the po said that mistubishi had done something to the exhasut at one time but why this? just asking if this is normal or what. thanks

 

Picture?

 

1: you have an awesome avatar haha
2: i don't have one right now, totally thought i had on on my droid but apparently not haha ill get one up here tomorrow.

but i mean its a simple question though, isnt there supposed to be a flange there? just behind the cat?

 

Snapped some pics of it real quick like. Looks weird to me, but is this not supposed to be like this?

 

come on does noone know if this is stock or why it would have been changed this way?

 

that is definitely not stock. that is not the stock cat or catback for the evo 9 either.

 

So thats not even the stock cat? or the same as the piping after it? grrrr. this is stupid, why the hell is it that everytime i find something wrong with this car, it was done by the place the previous owner took it to for warranty work.

 

Def looks like the stock cat. But im not sure about the rest.

 

if it were the stock cat the rear o2 sensor would be installed in it instead of in the catback. also the piping would be the same size as the catback

 

so let me take a wild guess and say that this is why im getting a cel...

 

to know for sure you would have to see what the code is first and then it could pretty much tell you, like i know the rear o2 cel is P0420

 

ok, but if thats it, im gonna have to get one of those o2 extender things to shut that off? im gonna just make a test pipe so i think id have to get one of those anyways.... sorry, the last car i built was my z and i was running a haltech so i didnt have to worry about this crap haha.

 

you can remove the rear o2 sensor without any ill effects, the code can simply be disabled within the ecu. i dont run a rear o2 and havnt for the past 7 or 8 months and dont have a check engine light

 

Yeah but what would I need to disbale the code? There's no like tuner shops or anything up here in northern wyoming haha.
