Unleashing our newest line of performance racing mufflers- The Aluminum PowerMufflers. Hand-crafted from 6061-T6 USA made aluminum, these mufflers incorporate the same straight-through design of our typical bullet mufflers, but with precision machined billet end plates, larger diameter bodies, and larger volume of packing scrubble and attenuation space. These are perfect for lightweight, performance applications needing a muffler with increased muffling potential.
