Every effort was made in addressing the overly quiet sound of the stock OEM exhaust while designing an exhaust worthy for an \"M\" car. Combined with the Active Autowerke mid-pipe and catted downpipes, this offers a complete system upgrade. Available in both models, this axle-back exhaust gives your BMW the deep, throaty growl a car of its caliber should have had from the factory.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003e304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003eLow, deep sound with stock valve control\u003c\/li\u003e\n\u003cli\u003eEach exhaust test-fit on Active Autowerke's F97\/F98 exhaust fixture\u003c\/li\u003e\n\u003cli\u003eGuaranteed to fit all F97\/F98 BMW X3M\/X4M\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x rear axle-back exhaust\u003c\/li\u003e\n\u003cli\u003eAll necessary installation hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eReuses the OEM valve actuators for factory-style valve control.\u003c\/li\u003e\n\u003cli\u003ePart of a complete Active Autowerke X3M\/X4M system — pair with the \u003ca href=\"https:\/\/x58cartel.com\/products\/active-autowerke-bmw-s58-f97-f98-x3m-x4m-downpipe-11-064\"\u003eS58 F97\/F98 Downpipe\u003c\/a\u003e and a mid-pipe (\u003ca href=\"https:\/\/x58cartel.com\/products\/active-autowerke-catted-midpipe-bmw-supra-b58-fits-f-g-chassis-up-to-2024\"\u003eSingle Mid-Pipe\u003c\/a\u003e or \u003ca href=\"https:\/\/x58cartel.com\/products\/active-autowerke-equal-length-midpipe-bmw-s58-f97-f98-x3m-x4m\"\u003eEqual Length Mid-Pipe\u003c\/a\u003e).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePART NUMBER\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e11-103 (Brushed)\u003c\/li\u003e\n\u003cli\u003e11-103B (Matte Black)\u003c\/li\u003e\n\u003cli\u003e11-103C (Carbon Fiber)\u003c\/li\u003e\n\u003cli\u003e11-103CB (Carbon Over Black Chrome)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eVEHICLE APPLICATIONS\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eChassis\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003cth\u003eYears\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eX3 M (incl.
