{"product_id":"5-7l-hemi-cat-back-exhaust-system","title":"5.7L Hemi Cat-Back Exhaust System","description":"The Mopar P5155283 is a genuine OEM cat-back exhaust system engineered for optimal performance and sound. Constructed from aircraft-quality T304 stainless steel, it features durable mandrel-bent tubing and polished tips, complete with quad exhaust tips bearing the Mopar® logo. This bolt-on system is rigorously tested to deliver horsepower and torque gains, alongside potential improvements in fuel economy.\n\nThis exhaust system is specifically designed for vehicles equipped with the 5.7L Hemi Engine. Based on available fitment information, it is compatible with the 2013-2014 Dodge Challenger models, specifically the R\/T trim with the 5.7L V8 - Gas engine. Installation is straightforward as a bolt-on application, though professional installation is often recommended for exhaust systems to ensure proper fitment and performance.\n\nOwners have reported a satisfyingly throaty sound from this Mopar exhaust, described as having just enough muscle to be noticeable without being overpowering. While direct performance gains can be difficult to quantify without a custom tune, the free-flow design aims to enhance engine breathing. Some users have noted a slight internal droning sound at approximately 2000 RPM, but generally find the sound profile to be characteristic of a true Mopar vehicle.","brand":"Mopar","offers":[{"title":"Default Title","offer_id":52664225333560,"sku":"P5155283","price":400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687547703.jpg?v=1784335475","url":"https:\/\/store.motormia.co\/products\/5-7l-hemi-cat-back-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
