At ~21.5 kg, this is a substantial component — freight shipping may apply depending on your location; contact us before ordering if you need a shipping quote. When replacing the manifold, it is best practice to replace the exhaust riser, elbow, and all gaskets at the same time to avoid a repeat job. Confirm engine model, year, and serial number compatibility before ordering.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51037590650916,"sku":"47-19572","price":604.59,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/251c379f-e151-4212-8bfc-916780882f14.png?v=1783624019","url":"https:\/\/marisolmarine.com\/products\/sierra-exhaust-manifold-47-19572","provider":"Marisol Marine Company","version":"1.0","type":"link"}
