Who needs them?

The bigger body Magnum oval muffler is great when you dont have much space for the rear muffler, or when you cant fit a resonator.  Work great on a range of single exhaust system vehicles. The rear chamber makes fitting options easier, and the chamber also helps with quietening. Not an ideal choice for turbo applications however.

More size more packing and more inlet options than the 8inch version we offer.

Customised to suit

We can customize these to suit your application, track street strip or oval we have you covered!! Our factory is the leading custom muffler manufacturer in the country with all our own in house machinery we offer an extremely quick turnaround time, just ask!

Greater noise reduction

These baffles offer reduced noise levels over 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 rigours of daily use. 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.
