Big Sound and Bigger Flow for Maximum Output Vehicles. The Big D Series from Black Widow is designed for those who want an unmistakably aggressive tone and unrestricted exhaust flow. With a large 7-inch body and straight-through internals, this muffler produces deep, growling exhaust notes that turn heads on and off the track.
Performance Without Compromise in Extreme Conditions. Made from tough 409 stainless steel, the muffler resists heat, moisture, and vibration. It’s ideal for vehicles with large engines and aggressive cam profiles where maximum flow and sound are a priority.
Installation. This product must be welded or clamped into place. Custom fabrication may be necessary depending on pipe routing.
Application. This Black Widow Big D Muffler fits universal applications; some adaptation may be required.
