My 96 Cobra vert has twin Flow 40s with an h pipe. It sounds great except for 1900-2000 RPM (severe drone). I have read a few ideas to help:
1. Put Dynamat on the body above the mufflers. I'm not sure how safe this is...
2. Strap something solid and fireproof to the outside of the muffler body to change the resonance frequency.
3. Add short glasspacks before the mufflers.
I want to experiment before spending $ to make major changes, so,thanks for your ideas/experience.
