N55 w/ Downpipe Issue

bhs0731 · 04-10-2014, 06:59 PM

Can anyone else confirm TMAP is the issue? I am nearly stock and this gives me issues with AC on.

I have a downpipe in the box and this has me scared to put it on since I dont have any local shops to help solve the issue. Is this a widespread problem on DCT N55s?

Anyone?

I'm running a COBB catted downpipe my car started going into limp mode after a cold start. Seems like it stopped warming the cat on a cold start and the RPMs settle fast. I tried turning the car on without starting it to let the fuel pump run and get the computer running and that seems to make the problem less frequent.

Any thoughts?

No issues other than intoxicating sound... Jb4 with Downpipe on PPK

Nice, what are your thoughts of trying to add the BMW PE to that?

I wonder how loud it is going to be when I go BMS downpipe w/ BMW PE and PPK1

got the JB4 stack on 2

To be honest the $$$ for performance exhaust, I'd rather fmic... Car sounds great at the moment, not sure how much better it could sound
