The story- I found a place online selling RSR Downpipes for $120. Great! I pick one up for my Tsi and luckily it bolts directly to my Apexi Dunk cat-back (eliminates the cat too), no problems...only took 20 minutes to install. I think everything is going well. I go out for a drive and notice that my Air/fuel gauge isn't reading anything...no bars, just a black screen. Then the CEL comes on. This didn't happen when I swapped the DP on my AWD. Any ideas? Did I kill an O2 sensor by simply bolting on a new DP?
