Who's throwing codes/limp mode with DP installed
Alright so I've been reading some of the members threads with recent issues after DP was installed. Wanted to start a thread where we can generate all issues along with all mods attached over stock. I had my Dinan exhaust, vrsf DP, and a mini cat. Everything was fine for about 200miles and than popped a check engine light. (Btw only have 700miles)
Haven't had any drivability issues like some other members have but def want to find a fix in case this does happen to me. The codes were for post cat O2 sensor and outside air temp sensor Mods Dinan exhaust vrsf DP only. |

Until all information is analysed and I have a clear answer my story does not really belong in this topic, but for now I can mention I had four limp modes on the autobahn at speeds above 210 up to 270 km/h, and I have an Akrapovic exhaust + down pipe with catalytic converter installed.
This is my story: http://f87.bimmerpost.com/forums/sho....php?t=1317706 A question from my end to the people in this topic; what kind of error messages do you find when you read out the on-board computer of the car? I would love to know if the DP installation throws similar messages across all of our cars. This way we can find a trend and see what the solution might be. MR |

This is the main reason why I always recommend our Sport Cat Downpipe over out Catbypass. Although yes, you can tune it out but why go through that hassle of it coming back on? All for what? A couple more horsepower. To me not worth it. Definitely interested to see where this thread goes and what issues people are having.

The check engine light isn't so much of a concern because well that's expected when you go catless but possibly going into limp mode or throwing other codes is where the issue is. Going catless has more advantages than just a few HP but I get it your trying to sell your product.

We offer a catless downpipe as well. But in reality besides some sound and a couple more horsepower there really aren't too many other advantages of going catless. I haven't had any of my customers going into limp mode as well. So I'm interested in seeing what issues cause that to happen. |

I've had a DP installed on my car the 2nd day I got my car, but mine has a 200cel cat so I didn't expect a code anyways. I have racked up about 8000kms already

Catless downpipe will throw a CEL code not limp mode.
If you are getting limp mode, something is wrong with the car, has nothing to do with downpipe (unless you damaged the O2 sensor when replacing the stock DP)
