Designed for drop-in fitment with the GM LS1 engine paired to a Camaro F-body T56 6-speed transmission, using the ER Spec swap mounts. 1-3\/4-inch primaries into 3-inch collectors, mild steel construction.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eLS swap headers are one of the components most likely to cause clearance problems on any LS swap because every chassis has different frame rails, steering shaft routing, and firewall geometry. These headers are specifically dimensioned for the Genesis Coupe with the GM LS1 engine on ER Spec swap mounts, so they drop in without modification. 1-3\/4-inch primaries support naturally aspirated builds in the 400-500hp range and deliver good throttle response on a street\/track setup.\u003c\/p\u003e\n\n\u003ch3\u003eCritical Fitment Requirements\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eThese headers are only guaranteed to fit when using the complete LS1 swap setup:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2010+ Hyundai Genesis Coupe chassis\u003c\/li\u003e\n\u003cli\u003eGM LS1 engine\u003c\/li\u003e\n\u003cli\u003eCamaro F-body T56 6-speed transmission\u003c\/li\u003e\n\u003cli\u003eER Spec LS1 swap mounts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eDifferent swap mounts, a different LS variant with significantly different exhaust port geometry, or a different transmission will likely cause clearance issues.
