• Developed for an engaging, refined note with minimal cabin boom and no intrusive drone
• JET-115 carbon fibre tailpipe finishers deliver a subtle motorsport look that suits the 128ti perfectly
• Direct bolt-on to the OE mounting points behind the particulate filter, no cutting of the filter section
• Built by Milltek Sport to exacting standards with beautiful welds and a high-quality finish
