Additional information


These popular 6” AdrenalinR mufflers are great value and high performing – perfect for smaller turbo engines and mildly modified vehicles.  Their compact size makes fitting a breeze, and we carry full range of inlet sizes available on the shelf.

Greater noise reduction

Our patented louvre baffle based mufflers have been a real hit giving what some engine tuners believe is the edge over the competition. The AdrenalinR edge!!

These baffles offer reduced noise levels over the conventional designs by disrupting and dispersing soundwaves before they reach the Db meter. The results are lower Db reading and an increase in flow through the spiral scavenging effect.

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 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 needlemat fibreglass blanket acts as the final noise insulator which results in quieter, deeper notes singing from the rear of your vehicle.

Superior construction

Our muffler bodies are embossed which adds significant strength to the muffler, eliminating unwanted resonance to provide an improved tone with a deeper note. The solid construction is more resilient to the rigours of daily use and scrape damage is minimized by our unique mounting strap design.

AdrenalinR Performance Mufflers have spotless consistent welds, we utilize Automated Welding Technology for superior welds.
