To give an update on my Ark midpipes, Magnaflow catback & exhaust tips install this past Thursday, it has overall been good.
Two things that have been good:
1. The look and sound is great, it has a nice deep rumble to it, and I love the look of the akrapovic carbon fiber tips.
2. Over the weekend, and tracking with my Draggy app, I got to 60MPH in 4.37 seconds on a full tank of gas with temp around 50 degrees F. My previous best was 4.55 seconds, and that was with less than a gallon in the tank with temp around 45 degrees F. With the VT Big Mouths and this exhaust it definitely feels a bit quicker...at least my Draggy times show it.
Two things that aren't so good, one more than the other:
1. The far outer passenger side exhaust tip is rubbing a little on the plastic bumper cutout, even after using a dremel. Need to think of a way to stop that from happening.
2. Yesterday morning I accelerated out of a stop light, there was a loss of power then the check engine light came on. I got home and plugged in the OBD2
scanner and saw the code was P0234 (Engine Overboost Condition). The temp was around 20 degrees F when it happened. I had to work throughout the day, then started it back up in the evening and the check engine light was off. I went for a quick 15 minute drive, and she was back to normal, drove beautifully. Not sure what it was, maybe the wastegate was stuck? Bad sensor? Or do these cars just not like driving aggressive in cold weather?
I've heard of overboosting from installing
aftermarket primary (catless) downpipes, but not from the midpipes and catback. I'm keeping an eye out and being cautious, hoping this doesn't happen again. And if it does, should I contact the dealer to have them check the wastegate sensor?
