Anyhow, if you want to get rid of resonance/drone you'll have to go w/ an OEM exhaust system. Can't recall any aftermkt systems w/o drone at some RPM or another...

Good luck

NHP exhausts do not drone at any RPM

In the past I heard that Eisenman supplied Porsche with some of it's oem exhaust systems. However, they're most know for their aftermarket exhausts. They most notably cater to the BMW crowd. Interestingly, rumor had it, a few years back they pulled the plug on their US importer for allegedly selling counterfeit versions of their exhausts .

Every exhaust drones. It's a natural occurrence due to physics involved. What's important is muffling, or minimizing the drone or the shifting of it's frequency to acceptable/tolerable levels. Whether or not you agree it's still true. Glad to know NHP minimizes it to very acceptable levels w/o muffling sound too much. OEM's make it tolerable by muffling the sound immensely.
