An illuminated toggle switch wires through a heat and water-resistant harness to an electronically actuated valve. Open it up for a deep unrestricted tone. Close it down for towing, daily driving, and early starts. Precision TIG-welded from 304 stainless steel and back purged so the inside of every weld stays clean and corrosion-resistant. Simple, tough valve design built to run hard and hold up. Fits most 4\" diesel exhaust setups.\u003c\/p\u003e","brand":"HMD Fabrications","offers":[{"title":"Default Title","offer_id":44283444789290,"sku":"4INCH_VARIABLE","price":499.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0695\/5928\/7850\/files\/hmd-4-inch-variable-muffler-304-stainless.png?v=1777014960","url":"https:\/\/hmdfabs.com\/products\/new-4-variable-muffler","provider":"HMD Fabrications","version":"1.0","type":"link"}
