Who needs them?

These low profile mufflers tuck up nicely out of the way while still muffling as well the 7″ round muffler. Get that big bore look

Spiral Louvre technology

We use SANPRO Industries Patented Spiral Louvre Duct Baffle Design, giving a spiral effect to the exhaust gases as they pass through the muffler. These baffles offer reduced noise levels over the conventional perforated designs. They are particularly effective at reducing neutral throttle drone.


Our muffler bodies are ADRENALINR embossed which adds significant strength to the muffler, eliminating unwanted resonance to provide an improved tone with a deeper note.

Solid construction

The solid construction is more resilient to the rigors of daily use. Scrape damage is minimized by our unique mounting strap design.

Spotless consistent welds

AdrenalinR Performance Mufflers have spotless consistent welds, we utilize Automated Pulse TIG Welding Technology for superior welds. Please note the rolled tip design does not allow for fitting of our removable silencer designs.
