The Milltek Sport Filter-Back Exhaust System is engineered to enhance performance, acoustics, and visual appeal for high-performance vehicles. Constructed entirely from lightweight titanium, this system replaces the rear section of the exhaust—from the catalytic converter to the tailpipes—with free-flowing 3-inch pipework. - Full titanium construction for superior strength-to-weight ratio - 3-inch diameter pipework enhances flow and reduces back pressure - Rear silencer bypass for increased exhaust sound and performance - Designed to replace the system from the catalytic converter back - Compatible with Porsche Sport Exhaust (PSE) systems
