I had 2 codes reading P2098 & P0410 auto shop was saying it would cost around 2000 to fix those two problems .So I took a look under the car carefully since one code read exhaust leak near o2 I looked at it carefully noticed a slight gap were the welding came off of a restricter got that weld in for $40 talk about a diffrence car is so smooth & quiet so ended up getting a deep sounding exhaust with the money I saved on those rip off auto shop exhaust was 400 next is some wheels .By the way took it for emissions test pass it and before it was not able to pass becuase of those two codes.Hope this helps somebody with this trouble codes to.
