Additional information

Who needs them?

These mufflers are especially suited to big bore exhaust systems that need more muffling. We have also found them to work especially well on turbo diesel engines, and the performance increase from a free flow exhaust is remarkable! Can be used on any rotary or turbo engine also – even boats!

Greater noise reduction

These baffles offer reduced noise levels over the conventional designs. They are particularly effective at reducing neutral throttle drone.

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 rigors of daily use. Scrape damage is minimized by our unique mounting strap design. AdrenalinR Performance Mufflers have spotless consistent welds, we utilize Automated Pulse TIG Welding Technology for superior welds.
