Hi Doul, could you describe the sound of the rpi header during normal city driving, wot, etc. I had the evosport headers with my E-race, and sold the evo headers as i find it too loud for my taste. During normal driving, resonance between 2.5k-4k rpm is unacceptable. Do you experience this with you RPI header and E-race muffler setup? Your experience is highly aprreciated. How about posting ur video clip?
