Correct length and head geometry are part of the specified fastening arrangement. A generic M8 bolt may thread into the mounting point while still providing the wrong engagement depth or contact surface.\u003c\/p\u003e\u003ch3\u003eCommon reasons to replace\u003c\/h3\u003e\u003cp\u003eReplace a missing bolt or one with damaged threads, a rounded head, visible deformation or corrosion that has compromised its condition. Renew mounting hardware whenever the applicable factory repair procedure requires replacement after removal.\u003c\/p\u003e\u003cp\u003eDuring downpipe or exhaust service, inspect the mounting bracket, hanger and mating threads as well as the bolt. Looseness or rattling can originate from a damaged support, incorrect alignment or a different exhaust component. A replacement bolt alone will not repair those defects.\u003c\/p\u003e\u003cp\u003eCheck for a bracket that does not sit squarely, a damaged mounting hole or stressed exhaust alignment before tightening. Correct the underlying issue instead of using a longer bolt or additional tightening to pull the components into place.\u003c\/p\u003e\u003ch3\u003eInstallation and service notes\u003c\/h3\u003e\u003cp\u003eAllow the exhaust to cool and support the assembly using the factory service procedure. Confirm the original attachment location and compare the replacement with the fastener specified for that position.\u003c\/p\u003e\u003cp\u003ePosition the exhaust and bracket correctly before starting the bolt by hand. Follow the required tightening sequence and specification for the exact mounting point. Do not calculate a torque from the M8 diameter or transfer a specification from another exhaust fastener.\u003c\/p\u003e\u003cp\u003eUse thread treatments or replacement companion hardware only as directed by the repair instructions. Inspect receiving threads before assembly, and use a correctly fitting socket on the external hex head.\u003c\/p\u003e\u003cp\u003eAfter installation, verify exhaust support, alignment and clearances. Check for contact with nearby components and investigate any remaining vibration or rattle. This individual fastener is not a complete downpipe installation kit or a gasket for an exhaust joint.\u003c\/p\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eVehicle\u003c\/th\u003e\n\u003cth\u003eModel years\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003cth\u003eChassis and transmission\u003c\/th\u003e\n\u003cth\u003eApplication restrictions\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eVolkswagen GTI\u003c\/td\u003e\n\u003ctd\u003e2015–2017\u003c\/td\u003e\n\u003ctd\u003e2.0L turbo gasoline, EA888 Gen 3\u003c\/td\u003e\n\u003ctd\u003eMk7, front-wheel drive; 6-speed DSG\u003c\/td\u003e\n\u003ctd\u003eDownpipe mounting-bracket hardware at subframe; match original bolt number and factory mounting arrangement.
