Alright so i have posted previously about bad cats and exhaust issues. I have new catless headers and a megan racing Y pipe installed currently. So my car is catless. I have tried spacers on both downstream sensors but have so far been unable to throw the codes. It’s just annoying having that ugly CEL and the flashing Traction control light which makes my TC off button useless. Wondering if anyone can give some more ideas. I been lookin at o2 simulators but not sure how that would work or where to get one. Might just take it somewhere and see if they can throw the codes for good. Seems like every time i get them gone they come back within 2 hours of drive time. Would just like the light off so i can know if something else is wrong and so i can use my traction control button. Thanks
