ISR Performance LS1 Swap Headers - Hyundai Genesis Coupe

The ISR Performance ER Spec LS1 Swap Headers are purpose-built headers for LS engine swaps into the 2010 and newer Hyundai Genesis Coupe. 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.

What It Does

LS 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.

Critical Fitment Requirements

These headers are only guaranteed to fit when using the complete LS1 swap setup:

• 2010+ Hyundai Genesis Coupe chassis
• GM LS1 engine
• Camaro F-body T56 6-speed transmission
• ER Spec LS1 swap mounts

Different swap mounts, a different LS variant with significantly different exhaust port geometry, or a different transmission will likely cause clearance issues. Verify your swap configuration matches before ordering.
