DIESELR Universal Twister/Auger Muffler

For serious diesel builders who want clean tone, strong flow, and zero drone.

Built for Performance & Longevity

This auger-style muffler features a high-flow, straight-through spiral core that improves exhaust velocity while keeping backpressure to a minimum. It’s TIG-welded from heavy-duty stainless steel to handle extreme temperatures and long-term use on daily drivers, tow rigs, or competition trucks.
