I don't see or understand how just a change in canisters can reduce db levels of the exhaust?
I've been in love with the sound of and have pleased with the gains of the HKS Hi-Power exhaust 60mm. But if I can gain more power while most importantly keeping the noise down just from a different design, then I will do it. My main concern here is that exhaust noise.
what's the difference in piping / resonator designs from the two exhausts you've had?
