We now offer the perforated baffle resonator as a standard product – they are proven to be both sought after and great sounding!

 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 BMW derived  perforated baffle. It offers a crisp, deep sound with full flow and minimal disruption to gas waves. Great for turbos where exhaust flow is maxed out and no restriction is suitable. Also great to quieten and improve note on any vehicle, especially if the exhaust note is a little “fluffy”.

3 stage sound absorption

Every single muffler we fabricate utilizes 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 needle mat fibreglass blanket.

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.

The ceramic matting absorbs noise and heat preventing the fibreglass from turning back to glass.

The needle mat fibreglass blanket 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!
