{"product_id":"axle-back-exhaust-system-11","title":"Axle-Back Exhaust System","description":"The Stillen 508275 axle-back exhaust system is specifically engineered for the 2008-2013 Nissan Altima Coupe (L33 chassis). Constructed from durable stainless steel, this system includes polished stainless steel tips, end pipes, and mufflers, ensuring longevity and a premium appearance.\n\nThis axle-back system utilizes 2.5-inch mandrel-bent piping to enhance exhaust flow, which is verified by significant dyno-proven horsepower increases. Drivers can expect noticeable gains in power and torque across the entire power band, with particularly beneficial increases at higher RPMs. The improved airflow can also contribute to better mileage per gallon during steady highway cruising.\n\nWhile designed for enhanced sound, the Stillen 508275 aims for a refined auditory experience. It produces a mild exhaust note at idle and during cruising, escalating to a more aggressive tone when accelerating under throttle. This balance makes it a suitable option for those seeking an improved exhaust note without an overly intrusive cabin sound, complementing the factory exhaust cutouts nicely and enhancing the vehicle's rear aesthetics with its dual polished, engraved tips.\n\nKey features include its stainless steel construction for durability and sound quality, polished stainless tips for a striking visual, and a Limited Lifetime Warranty. This axle-back system offers a compelling solution for Altima Coupe owners looking to upgrade their vehicle's performance, sound, and appearance.","brand":"Stillen","offers":[{"title":"Default Title","offer_id":52663852695864,"sku":"508275","price":602.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687715854.jpg?v=1784330164","url":"https:\/\/store.motormia.co\/products\/axle-back-exhaust-system-11","provider":"MOTORMIA","version":"1.0","type":"link"}
