{"product_id":"2-5-inch-stainless-steel-cat-back-exhaust-system","title":"2.5-Inch Stainless Steel Cat-Back Exhaust System","description":"The Mountune Performance mk3 Focus ST cat back exhaust system is meticulously engineered to enhance power, response, and exhaust tone. Constructed from 2.5-inch diameter AISI 304 stainless steel (EN58E) mandrel-bent tubing with precision laser-cut flanges, this system is built for longevity and performance.\n\nThe muffler assemblies utilize robotically TIG-welded AISI 304 stainless steel, ensuring a consistent internal diameter throughout. To control sound and eliminate undesirable tones like droning and booming, each muffler incorporates a three-layer hybrid synthetic sound absorption packing effective up to 900 degrees C. Slip-fit connections are strategically placed to facilitate easy installation and adjustment.\n\nThis cat-back exhaust system comes with a limited lifetime warranty from Mountune and is noted as not affecting the base Ford vehicle warranty. It is recommended to fit this exhaust in conjunction with a mk3 Focus ST Sports Cat \/ Downpipe for optimal performance. Please note that this exhaust is not compatible with Wagon models; a specific product is available for those.\n\nFeatures include 4-inch rolled edge, polished stainless steel tips with the Mountune logo, a full-width rear hanger for stable tip location, and heavy-duty \"boss\" type clamps.","brand":"Mountune","offers":[{"title":"Default Title","offer_id":52663050469688,"sku":"2363-CBE-AA","price":799.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687512627.png?v=1784323245","url":"https:\/\/store.motormia.co\/products\/2-5-inch-stainless-steel-cat-back-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
