Whether you want to make as much power as possible naturally aspirated, or are looking to run one of our M156 Stage 2 or a Stage 3 Supercharger Systems, it will be necessary to upgrade to long tube headers.\u003c\/p\u003e\n\u003cp\u003eTo make for the best power possible, the headers feature 2” primaries that allow for as much flow out of the cylinder head as possible. The large primaries and proper O2 sensor placement of these headers work extremely well when coupled with our Stage 2 and Stage 3 supercharger systems resulting in the best performance and drivability out of all the headers that are currently on the market.\u003c\/p\u003e\n\u003cp\u003e*Actual system may be different than picture depending on chassis.\u003c\/p\u003e\n\u003cp\u003ePackaged with the headers are 3” Stainless Steel Midpipes, and a 3” Stainless Steel X Pipe resulting in a bolt on installation* that retains the factory resonator and mufflers.\u003c\/p\u003e\n\u003cp\u003eWhen paired with Weistec ECU Upgrade and Weistec High Flow Air Filters, power gains are typically 90+hp at the wheels for naturally aspirated vehicles. These headers are required for Stage 2, and Stage 3 Supercharger Systems to achieve advertised power.\u003c\/p\u003e\n\u003ch4\u003eKey Features:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eAll Stainless Construction\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTig Welded\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e2” primaries\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eMidpipes and X Pipe\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eProper O2 Sensor Placement\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eExhaust Manifold Gaskets Included\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSignifigant Horsepower Gains\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eBolt In for most models*\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv style=\"font-size: 11px;\"\u003e*some models have weld in connector pipes.  All exhaust systems are made for left hand drive vehicles\u003c\/div\u003e\n\u003ch3\u003eVehicle fitment\u003c\/h3\u003e\n\u003cul class=\"fitment-list\"\u003e\n\u003cli\u003e2007-2011 Mercedes-Benz ML63 AMG Base\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWeistec part number: 01-156-00852-8 · UPC: 810089561503\u003c\/p\u003e","brand":"Weistec","offers":[{"title":"Default Title","offer_id":60049895653662,"sku":"WEI01-156-00852-8","price":5999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0759\/7965\/3406\/files\/m156exhaust1_85ca7c9f-aba0-458a-9ecb-b1393078c210.jpg?v=1790378547","url":"https:\/\/shop.signatureautohaus.com\/products\/weistec-m156-exhaust-system-ml63-01-156-00852-8","provider":"Signature Autohaus","version":"1.0","type":"link"}
