Who needs them?
Rotary owners – using these resonators on your naturally aspirated rotary will provide a crisp, deep note while removing decibels and taking the harshness from the exhaust note. Work great when combined with our big 7″ rear muffler for a road-legal combination, whilst still maintaining the deep pulse sound and full flow system.
V8 owners – using these resonators on your V8 will eliminate cruise drone while providing a crisp, deep exhaust note.
Work great when combined with our chambered oval V8 rear muffler pack giving extra muffled length, lowering the sound even further while retaining that throaty V8 rumble
How it works
The large port perforated baffle provides a deep clean note from the exhaust. The torque chamber at the outlet provides a pressure drop space, causing the next pulse wave of gas to collide with the chamber held gas. This design allows us to maintain a straight-through, full flow system. Backpressure is necessary for all naturally aspirated applications as it promotes the scavenging effect required to produce complete and clean burning of the fuel charge. The torque chamber – combined with the straight-through baffle produces those crisp exhaust notes we all want and helps the engine provide maximum power at the same time.
These great resonators are built here in NZ, made completely of stainless steel and packed with high-quality exhaust grade stainless steel wool. This provides protection by diffusing the gasses through the wool so the sound absorbing fibres are not pushed through the baffle holes under pressure.
We build ’em strong with the best materials, and are so sure of the quality we offer a lifetime warranty!
