If you want a DP forget about Dinan thats how it is..
Even catted DP might throw a CEL.
- Sell Dinan S1
- Get a Flash tune that has better gains and cat delete in the software

Or you can get a Backend Flash from MissionPerformance and continue using your Dinan S1

Thanks man! I will hit up mission performance

Could you explain what a backend flash is? I too have a Dinan s1 and want to add a dp. Thanks in advance.

Dinan is a stage 1 tune, it is not meant to work with high flow downpipes

Best bet is to get a JB4 and add downpipes but if you want to keep Dinan i recommend the Fabspeed downpipes, they are the best at not throwing a CEL

Backend flash is when you use a flash tune with your piggy in this case Dinan

You need to remove the ECU of your car send it to a tuner and they will upload a map for you so you can make more power
