The Milltek Sport Primary Cat-Back range replaces all OEM parts of the exhaust system after the primary catalyst assemblies and removes the secondary catalysts. This creates a freer flowing system with improved sound and throttle response. All performance exhaust systems are designed for a wide range of vehicles. The research and development team works throughout the year to deliver solutions for performance exhaust requirements. All products are made in the UK and distributed to more than 90 countries worldwide. - Replaces OEM exhaust components after the primary catalyst assemblies - Removes secondary catalysts for improved flow - Designed for enhanced sound and throttle response - Manufactured in the UK and distributed globally Specifications: - Pipe Diameter: 76.20 - Race Product: No - EMarked: No Kit comes with: - MSNI104: Y Pipe - MSNI104 - MSNI106: Connecting Pipe - MSNI106 - MSNI107: Link Pipe - MSNI107 - MSNI108: Rear Silencer - MSNI108 - MSNI109Ti: Brushed Titanium GT (round) 127 Exhaust Tip - MSNI109Ti Vehicle Compatibility: - 2009-2015 Nissan GT-R R35
