Good for your V8

These mufflers are especially suited to V8 applications we offer them as an alternative to the cheap and nasty mufflers being pushed for use on V8s by importers. If you want a better sound and more power for your V8 choose AdrenailnR! A twin inlet/outlet design increases flow while our louvre baffle design reduces unwanted noise and neutral throttle drone!
More size more packing and more options than the 8″ x 5″ version we offer.

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 Pulse TIG Welding Technology for superior welds.
