Dinan enlarged the tubing to 83 mm (against 80 mm stock) and fed it into a muffler using the absorption and reactive technologies common to every Dinan exhaust to cut backpressure — for more power and a sporty tone that stays civilized at low speed and turns pleasantly aggressive under hard acceleration, helped by the retained computer-controlled valves. Low-RPM drone is engineered out, so the cabin stays intimate rather than drowned.\u003c\/p\u003e\n\u003cp\u003eThe system is crafted entirely from T304 stainless steel, TIG welded and brush finished.
