{"product_id":"3-exhaust-cat-back-system","title":"3\" Exhaust Cat-Back System","description":"The Retro95 3-inch performance cat-back exhaust system is specifically designed for the Nissan D21 Hardbody. It features a true over-the-axle layout, constructed in the USA from durable 16-gauge 306 stainless steel for longevity and performance.\n\nKey features include mandrel-bent tubing for optimal exhaust flow, a 5-inch flex pipe to absorb engine movement, and robust V-band clamps for a secure connection. The system utilizes OEM mounting points for easier installation and comes with a 10.9-grade hardware kit, aluminum spacers, and an adjustable tail hanger for DIY muffler setup.\n\nThis exhaust system is engineered to support over +500 HP with minimal bend angles and a straight-pipe design. It's lightweight, weighing under 11 KG, and maximizes clearance between the frame and axle. Confirmed fitment is for the 1990-1995 Nissan D21 Hardbody Regular Cab with the 4 Cylinder KA24E engine, Short Bed (104.3\" wheelbase), 2WD\/RWD, and either automatic or manual transmission.\n\nInstallation may require spare tire removal and rear bumper trimming or removal. A single M8 hole drilling is necessary for the tail-pipe-strap assembly. For 1986-1989 and 1996-1997 models, a template is available to check fitment, but the O2 bung is not included.","brand":"Retro95","offers":[{"title":"Default Title","offer_id":52689365664056,"sku":"321060017","price":775.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687607073.webp?v=1784905718","url":"https:\/\/store.motormia.co\/products\/3-exhaust-cat-back-system","provider":"MOTORMIA","version":"1.0","type":"link"}
