    DMH Exhaust Cutouts Stability Control Issue

    So...Had my DMH cutouts installed last week. Absolutely love them. One issue...When I get on her hard in 1st or 2nd, I occasionally get the "stability engaged" message. I don't feel like I'm losing any more traction than I did before? Wondering if it's the absurd noise and vibration coming from the cutouts affecting some sort of sensor related to the stability control? Anyone?

    We ran into this four years ago - StabiliTrak yaw sensor located under the center console.

    Re: DMH Exhaust Cutouts Stability Control Issue

    Bumping an old thread!! (Hey, at least I did a search...right?!)

    Has anyone experienced this issue? I just had my DMH low-profile cutouts installed right under my console and I've gotten the "Stability Engaged" message already. I've got a fairly well-cammed LS6 with Kooks headers and no cats. It's loud as hell and shakes the car quite a bit under full throttle.

    When this happened yesterday is actually pulled the car to the right quite suddenly. Is there a way to dampen the yaw sensor in my center console?

    Does "Competitive Mode" still give you the issue?

    Competitive mode does turn off the Stability Control system but I was wondering if there was a more permanent solution (besides never opening my cutouts!!).

    I got this a bit when i first had mine and really got on it in the short gears, but it did go away... i've had mine for over 3 years now (had to change em out twice) but i haven't seen it in a long time. My V is stock power wise though

    Re: DMH Exhaust Cutouts Stability Control Issue

    i have DMH low pros right behind my kooks and kooks cats. They are equally loud and add vibrations in the floor. I did have the stability kick on if i remember right? Very rare if at all. I may be confusing it with T/C and I think my wheels are starting to just slip. Does this happen on a simple straight? (just to eliminate the variable of lateral Gs)? I will try this tomorrow. If it is related, doubt there is a fix given the location. Never thought about the yaw sensor.. Exactly where is it?

    Re: DMH Exhaust Cutouts Stability Control Issue

    Bneal - I have no idea where the yaw sensor is. I just remember seeing this thread (or something similar) years ago and it stuck with me. It happened on the straights and has happened a few times when I really open it up.

    I could not believe how much vibration and noise (in a good way) these cutous caused. Absolutely jaw-dropping...although a little embarrassing when cruising and the whole car is vibrating and rattling.

    I'm hoping that it goes away and, yes, it is only in the short gears.

    Why did you have to change them (cutouts) out twice?

    Thanks Rippy!

    Any thoughts on how I can "disable" or dampen the sensor so that the floor vibrations don't cause it to enable. I'd still like it to be functional for normal everyday driving.

    Re: DMH Exhaust Cutouts Stability Control Issue

    vibrations on the floor shouldn't have any effect on the yaw rate sensor ...

    Fair enough. I'll have to investigate further but there does seem to be a direct correlation between the vibration/sound caused by the cutouts on the floor of the vehicle directly under the yaw sensors and the Stability System Control tripping on...

    Re: DMH Exhaust Cutouts Stability Control Issue

    There's definitely some sort of correlation. I've taken the V out on 2 or 3 occasions with just open headers. It sounds like the biggest baddest thing on the road, but when I would get on it the stabilitrak would pop on a lot. Seems the vibs were affecting the sensor. I think not just myself sitting in the car, but other people in cars next to me could feel the vibs it was putting out.

    Re: DMH Exhaust Cutouts Stability Control Issue

    well you could have a wiring problem

    vibrations could be messing with a loose connection (or a broken pin in a connector)

    stuff like that
