We are working on the resonator either this evening or tomorrow AM, but in the meantime I have been working with a few engineers in a few other industries who have had good success at using a variety of acoustic and quarter wavelength tuning by using a variety of helmholtz resonators to smooth pulses in gas lines as well as to reduce noise in compressed gas systems (intake tuning on reciprocating compressors, etc). These guys have a ton of real world knowledge and are pretty entertained with the work we're doing here so they're eager to help us out in any way they can facilitate. Obviously our primary goal on this exhaust is to tune out cabin drone. But the reality is that we should be able to use similar concepts to impact the scavenging potential of the exhaust and limit reversion. I'm headed out in a few to pick up a variety of smaller mandrel bent tubing so that we can work within the physical constraints of the car to get the right resonators in place with minimal weight and best fitment under the car.
My overall goal would be to build a system that improves scavenging and reduces drone simultaneously - something we stumbled up on with the Genesis 3.8R axleback exhaust.
