Outside, the tone is purposeful and mature with a premium finish to match. It looks every bit as special as it sounds.\u003c\/p\u003e\n\n\u003cp\u003eBuilt from heavy duty 16 gauge 304 grade stainless, the system is designed for long term use on UK roads. It mounts to the original hangers for a precise, rattle free fit and includes the required hardware for a straightforward installation. The visual highlight is a pair of oversized quadrilateral black ceramic coated tailpipes, each laser etched with the Dinan logo, measuring over 8 inches wide and 4 inches tall. The result is a more assertive rear end that complements the G30’s clean lines.\u003c\/p\u003e\n\n\u003cp\u003eWe have installed and run this system ourselves at MJ Modifications and customer feedback has been consistently positive for sound quality, fitment and finish.
