Will this work? I got a ref ticket and i cant pass smog with a hahn catback so i figured i would also swap my lsj dp for a 2.2 dp with 2 cats... it would be cheaper

 

you cant pass smog with a hahn cat-back? its after the last emissions control device. it should barely alter emissions.

 

well i am having problems with my throttle body could that be the reason?

the hahn is all i have left on the car besides my stg 2

 

did you happen to get the 5 gas readings? i could help you out if i knew them. if you are having problems with your throttle body it could be causing a rich or lean condition increasing hydrocarbons, altering carbon monoxide, possibly increasing NOx, altering co2 and o2 levels

 

yeah my throttle body is bad... i keep throwing a code that sends me into limp mode but i just clear it with my obd2 scanner... then sometimes when i start it in the morning it almost dies and wont fully stay at idle... i am pretty sure i need a new throttle body.. but not only that but with the hahn i didnt pass my decibel test either lol

 

maybe you just need to clean it or the sensor...

 

i already cleaned it and it still does the same
