That is great news to hear you have no CEL without a simulator! How many miles on the setup?

I finally got the headers installed at the dealer on Wednesday and I got the car back on Thursday. Everything went smoothly for the installation, it took them about 7 hours to complete. The guys at the dealership were impressed by the quality and how easy it was to do the swap.
I bought brand new oxygen sensors so they did not have to remove the old ones

I can't believe how much it changes the car. It pulls much harder, it feels almost as if the normal mode is now what used to be the sport mode and the noise !!! It is now a very deep and raspy sound, I love it

I did a quick video of the startup but my phone mic did not do it justice. I will try to make another one while driving


Thanks a lot to Paul @ PPE and Joe Z for their fantastic products and customer service

I managed to get the car on the dyno, here are the results :
Red is with Joe Z intake and exhaust + RT cats
Black is with the PPE headers in addition to the above.

Nice, I love seeing everyone's numbers.. I assume 448.2PS is the same as 448.2HP? Or is there a conversion that needs to be done. It has been some time since I took French, but if I remember right puissance is power and Moteur is obviously Motor. Roues is wheels, so 390.5 to the wheels.

Just need to know if PS=HP or if there is a conversion that needs to be done.

Thanks

It needs to be converted, PS is the German acronym for HorsePower and is used as the power measurement unit in the metric system.
I did the conversion, it is at the end of the video : 442hp at the crank and 385rwhp it is quite good considering there are Random Tech cats in the way and they tend to be not up to the job when headers are installed
