OUR MOST AGGRESSIVE muffler and with virtually no restrictive qualities, the Widowmaker 6" (a.k.a. "THE NEIGHBORHATER") may be small... but packs a big sound! With a compact 6” x 5” footprint the Widowmaker 6" is ideal for tight space and, with Black Widow's patented internal hourglass design, reduces the opportunity for drone. All Widowmaker mufflers are backed by Black Widow's Lifetime Limited Warranty. Go to Warranty for details. NOTE: Because Black Widow mufflers are universal and not a direct OEM fit, we recommend installation by a qualified muffler shop. Recommended for off-highway use.
