Ar design downpipes after installation

hipopotish · 06-17-2011, 02:37 PM

Hi, I need some help here. I install the 3" catless downpipes, but while after I start the engine, the car shakes for about 10 seconds. I also install the o2 sim, but the engine check light is still on. Is it any problems with my car? I haven't install a JB or Cobb yet. My car is 2008 335i. Thanks for the help!!

Did you install the o2 sims correctly? What o2 sims are they?

Can you scan the car and post up what code you are getting.
