Our torque chamber resonators have been so effective at noise reduction that word of mouth has been our best marketing strategy! If you have a naturally aspirated vehicle and want to deepen the exhaust note, while reducing the noise and increasing the torque these are for you.
The Torque chamber resonators draw sound out of the exhaust using our own perforated baffle design based on BMW race exhausts and our 3 stage sound absorbtion mediums. The chamber deepens the exhaust note while slightly increasing the back-pressure for a balancing effect on the incoming air/fuel mixture and the exhaust gases leaving the vehicle resulting in a better performing vehicle.
Each and every one of our units are built here in NZ, comprised of T304 Stainless Steel, packed with high quality exhaust grade stainless steel wool, Ceramic matting and some tightly woven fibreglass needlemat blanket.
These units are 102mm outside diameter and 540mm long which can be customised for your application
Combined with an effective rear muffler these units are a must for any naturally aspirated Rotary engine. Take a look at this youtube vid a 13b PP running a set of these and one of our rear mufflers, Please note we make these in a range of lengths and inlet sizes 2" 2.25" 2.5"
