Resonator vs. muffler question... - ZR-1 Net Registry Forums

Hey guys,

My understanding is that our stock exhaust systems were Helmholtz-tuned to banish inherent resonance in 2 general ranges: 1800ish RPM and 3400ish RPM. In addition to deadening engine volume, of course, the resonator was tuned to handle one of these resonance tasks and the mufflers were tuned to handle the other...again, just my understanding so far.

So, if my understanding is correct, my question is: which is which? Do the mufflers quell the drone at 1800ish and the resonator at 3400ish, or vice versa? Or am I way off about the whole thing?

This kind of info might be really helpful, I think, for anyone considering any sort of modified exhaust system, as opposed to an off-the-shelf Corsa, B&B, etc.

Thanks!
Chris
