I didn't notice it if it did! You can definately feel it pull, though!

you compairing it to stock or the hrc ?

shy of an all out drag pipe I dont think the rossier is going to lose anything anywhere to any other pipe
imo

you will gain power throughout the whole rpm range

more gain low to mid but top will be better also.

the throttle response will be real nice and crisp

You will pick up hp through the whole range. My rossier system felt better than my hrc pipe with a hmf sport slip on. I did back to back test runs.

I dyno'd several pipes back to back to back and the Rossier made a little more peak than the next best pipe. But after the peak to the rev limiter it was far better than anything else. If I remember corectly it was like 4 hp more at the rev limiter. So to answer your question you will definately NOT lose top end. Plus you can bolt on a supertrapp set up to it if you need to add a sparky or quiet it down.
