i dont think so buddy.
the f7 is a top end pipe the power comes on way up the the rpms
the shearer comes on way faster in the lower rpms
i tend to disagree, i have damn good low end on my power pros and the power rolls on smoothly all the way through the RPMs, it def smoothed out the power band hit that i had with my FMF and DG... yet it added more on top, for my bone stock motor, def the biggest bang for the buck
my blaster doesnt mind being bogged now
btw, FMF and most other left bend pipes have no over-rev (besides sheerer)
