who said I have an electrical problem? Car has been to BMW 2 times since the cutouts have been installed without incident. They even know the cut-outs are installed....I also installed HID foglights that I needed to tap into the battery without incident as well.....

sounds great
did eliminating backpressure set any codes at WOT? I am guessing not since your mods are well downstream of the O2 sensor.

Is there any other place where the cut-outs can be done on the exhaust? I mean a place further down closer to the mufflers.
The sound is awesome, though I would prefer a lower rumble.

check out this link.... http://www.bimmerpost.com/2010/08/09...haust-cutouts/ Keep in mind that the flaps are 100% adjustable....meaning you can open them 5% or 50% and etc....This adjustments also changes the sound of the exhaust..... Last edited by dmetuning; 11-15-2011 at 08:59 AM.. |

Middly, Do you feel any power difference, or have you been able to measure any improvement in acceleration?
It sounds really good. I don't think you were even redlining in you vid. Also I know a turbo car allways sounds much better under load |

Off the line, its better that the flaps are closed since the turbos need some back pressure to spool faster. I end up opening the flaps, just slightly, as I am approching 70MPH and I feel a big difference as the car is accelerating from that point all the way up. The flaps have provided better high end acceleration that I can feel that wasnt available before. My car ran 12.4 at 110MPH with only Dinan Stage1. Since then, I have installed Stage2 and the exhaust and I am hoping to get back to the track in NJ on Nov 20. We will see how both of these mods affected my times. I will post the results once I have them. |
