{"product_id":"n1-cat-back-exhaust-system-70-80mm-pipe","title":"N1 Cat-Back Exhaust System 70-80mm Pipe","description":"The A'PEX-i N1 Cat-Back Exhaust System is engineered to enhance the performance and sound of the 2002-2007 Subaru WRX\/STI (GDA\/GDB models). This system is designed as a direct replacement for the factory exhaust, aiming to improve exhaust flow and deliver a more aggressive tone. The N1 series is known for its performance-oriented design.\n\nConstructed with quality materials, the system features a main pipe measuring 70-80mm in diameter and a prominent 115mm exhaust tip. Specific details on materials like stainless steel or titanium are not provided in the available evidence, but the N1 line generally emphasizes durability and performance.\n\nInstallation of this cat-back system typically involves removing the stock exhaust components and fitting the A'PEX-i N1 system in their place. No specific post-installation requirements or tuning are mentioned, suggesting it's a bolt-on component.","brand":"A'PEX-i","offers":[{"title":"Default Title","offer_id":52686936637752,"sku":"161AKF01","price":1099.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660182839.jpg?v=1784878658","url":"https:\/\/store.motormia.co\/products\/n1-cat-back-exhaust-system-70-80mm-pipe","provider":"MOTORMIA","version":"1.0","type":"link"}
