well, finally got around to installing the dynomax bullet today. Put it right before the corsa, and man, the difference is phenomenal. It still has a deep idle, and is quiet just like i like it, hard to believe the bullet toned it down, but it sounds great. NIce, crisp and clean and not as much drone and raspiness. thanks to shelton(truckshop) for the advice. and others as well. will hopefully get a video soon.
