Utilizing an internal chamber/collector allows this muffler to act as both a resonator and a collector! These are great where space is an issue or noise is a real problem.  Also a good option where twin tail pipes or shotgun tips are required.

How it works

The gas travels through a single louvre baffle and enters a rear chamber. The chamber can have smaller outlets than the inlet size, which slightly increases the pressure in the chamber and produces a gas flow disruption with the incoming gas. This increases backpressure slightly, helping to quieten the exhaust note and increase the scavenging effect on naturally aspirated engines.

Option 2 is to have the single inlet the same size as the twin outlets. This keeps pressure to a minimum and works better with turbo applications such as single pipe into twin-muffler setup or shotgun tips.

3 stage sound absorption

These resonators are made in-house completely from T304 grade stainless steel here in NZ so quality is assured.

Fitted to these mufflers are our patented spiral louvre baffles which disrupt and disperse soundwaves before they reach the Db meter. This results in a lower Db reading all while increasing the flow through the spiral scavenging effect.

They utilize our 3 stage sound absorption methodology which consists of wrapping the baffle in exhaust grade stainless steel wool, ceramic matting and a layer of tightly woven needlemat fibreglass blanket.

  1. The stainless wool breaks up soundwaves and creates a barrier preventing the packing from breaking up and exiting the rear of the vehicle prolonging the life of each and every muffler.
  2. The ceramic matting absorbs noise and heat preventing the fibreglass from turning back to glass.
  3. The fibreglass woven matting acts as the final noise insulator which results in quieter, deeper notes singing from the rear of your vehicle.

As we all know not every vehicle is the same so we offer a range of sizes to suit your application.

The longer the resonator means increased sound absorption for louder vehicles. If your chassis hits the ground and you don’t have the room then we can offer shorter resonators to fit what little gaps you may have.

If you have a custom build requirement just give us a call and we will work with you to find an agreed resolution.

We build ’em strong with the best materials, and are so sure of the quality we offer a lifetime warranty!
