Unlike most E46 M3 exhaust systems, the Valvetronic setup isn't hugely raspy - it just allows the straight-six to sing like it should. This system is offered in both stainless steel and titanium. Both systems are great, however the titanium components are lighter which is better for performance.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis valved section 3 connects to any section 2 and replaces the heavy suitcase muffler. When the Valve is open the true E46 M3 S54 sound experience is unlocked with an incredibly raw engaging sound throughout the entire rev range. When the valves are closed the car is returned to a stock-like sound level for that stealthy experience. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/xscH6YlwvDs\" height=\"315\" width=\"560\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003ePRODUCT SPECIFICATION\u003c\/h2\u003e\n\u003cp\u003e- Fully Mandrel bend for maximum flow\u003cbr\u003e- Precision TIG welds for high strength\u003cbr\u003e- Constructed of brushed T304 stainless steel or Ti 6Al-4V. - Grade 5 titanium \u003cbr\u003e- Rapid open \/ close valve function\u003cbr\u003e- 21.7 LBS Lighter than the factory exhaust\u003cbr\u003e- 100% REVERSABLE, always able to go back to stock at any time\u003c\/p\u003e\n\u003ch2\u003eCOMPATIBILITY\u003c\/h2\u003e\n\u003cp\u003e- BMW E46 M3 (\u003cspan data-mce-fragment=\"1\"\u003e2001-2006)\u003c\/span\u003e\u003c\/p\u003e \u003cem\u003e\u003cstrong\u003eDISLAIMER: Valvetronic Designs is an aftermarket exhaust manufacturer based in the USA.
