Swwweeeeeetttttttt! I just got back from riding and was very impressed with the performance of this pipe. Way more responsive and quicker in the low end and it feels like it added power throughout even though I went with the low-mid header. The main thing I noticed is how much more confidence it gives me to get on the throttle later if need be because I can lay down the power so much faster now. If I do get out of shape in a rythmn section or out of a corner I can back it off, straighten it out and know that I can still make the gap even if I'm late getting on the gas. MRD is definitely one of the best values in MX!
I know exaclty what your talkin' about. When I'm warming up to a track it takes me a while to get my corner speed down, now I can still hit every jump no matter how slow I take a corner or if I take an inside or outside line. I also noticed that the power never flattens out.
Something that you'll start experianceing when at the track is the people with the huge @ss pipes coming up and looking at your bike, woundering why your pipe doesn't stick out a mile.
