While driving a near-stock ZR1 (C6) with just Sport Exhaust I couldn't help but notice an obnoxious resonance around 5500rpm. I haven't experienced this with any other car and I don't experience it with any other exhaust system on this particular car so I was wondering if anyone else has noticed this or if it's an issue unique to me and my sound system.
