Exhaust only out of one side
1st I will say is I thought I knew how the exhaust should work but I am 675mi into my break in period and i don't think the l/h side of the exhaust has opened. I have been in comfort mode for the whole time...does it just open in sport? Need to be driven hard? I did a long highway drive Sunday and when I pulled onto my street I stopped and checked the outlets...the left side is completely cold. The right has some soot in the pipe but the left side is completely virgin...
Can someone enlighten me? |

The left side valve open rate is heat related and it takes place up front with aux pumps...so go in and have it checked. I know of three in our area, and they all have left side open up in about 35 to 40 seconds. I don't think comfort as anything to do with it...but I could be wrong on that. The electronic action back there on left side is actuated by up front temps in intake.

That is what I want to hear....I will re-evaluate when it is broke in. Right now i only drive in comfort and below 4k per instructions. I try to vary the load the best I can and am not using cruise.
I had noticed after my 1/2hr drive home the l/h exhaust pipe was cold.....and there is absolutly no exhaust residue inside like it is brand new. I am at 690mi so half way. Lookinfg forward to the 1200 milestone |

I studied the exhaust valve issue as well here are my results:
Exhaust valve closed when cold startup for 15 - 20 seconds and then opens. Valve open ALL THE TIME at least on idle on any driving mode. (When engine warmed up) Temps in my area are around 75-90F |

Ok so today I drove home in sport mode..."very easy" to abide by the break in rules and the exhaust was open when I pulled into the driveway. I looked up the exhaust and it was barely cracked open so I guess it opens and closes based on a bunch of parameters. All i know is that it never opened in comfort mode driven easy. At least I know it works....
