When I went from Berk HFC's to Motordyne ART (Advanced Resonance Test) pipes I literally could not tell a difference. The way the ART pipes are designed calms the sound down much better than a straight through Helmholtz design like most RTP's. The way the design engineers over at Motordyne explained it to me was its like blowing across the top of a bottle. The vortex changes the air flow therefore disrupting the DB. I have never had a customer I recommended these to come back and say they weren't happy.
