This system has been developed to offer Nissan GT-R owners the opportunity to tune their car to its full potential. It is constructed using high-grade lightweight titanium alloys, with individual parts cast in the in-house foundry. The one-piece construction link pipe has an increased diameter, measuring 101.6 mm (4 inches) for optimized exhaust gas flow. It is beautifully completed with larger handmade high-quality carbon fiber tailpipes (135 mm in diameter) over titanium inners and finished with an Akrapovič chicane design. With the addition of the mandatory Downpipe / Link Pipe Set (SS) or Link Pipe (SS), the Evolution Race Line is converted to a full system.
