Hey guys, got home today and to my surpise there was a package. AR Design catless Downpipes!!! So excited to hear them on the car along with my jb4 that will be getting installed at the same time. Tomorrow, I will have the DP's dropped off to get ceramic coated. I will keep every1 updated with pics and videos.

nice, do you have a pre dyno? it would be nice to see what sort of gains you get from the DP's...

I have a friedn that did JB and downpipes on his 135i with bmw performance exhaust and it sounded bad ass. are you going to leave it catless? If you are I hope your O2 sims will work better than his. He had the ones that plug direct into the JB unit and it wasn't 100%, he still got codes depending on the weather outside.

so what happens if you have to go in for an hpfp replacement, would you swap the dp's back to stock?

well I''ve had mine replaced a while back and no problems, nut I am really cool with the service advisor, all he told me was to take out the jb4 and I am good. If the dp is ever an issue he'll let me remove it and then they will work on the car.
