I just installed a set of the best E cutouts out there, DMH low profile Stainless Steel. They do rob low end torque, so I have been launching with them closed and opening them as soon as I get rolling. They seem to add some power but I really haven't been able to do any conclusive testing. The track was so crowded friday night I only got two runs in and never got to do an open/closed run. They are loud and I actually prefer the sound of the stock exhaust combined with the supercharger whine. Maybe when I get a bigger pulley they will really help out. I am waiting for my friend to upload a video, may take while. I also have yet to try thr 1/4 open method that was mentioned in this thread. Weekend is over so maybe next weekend I'll try it.
