ISR Performance Long Tube Headers - LS1 Swap Hyundai Genesis Coupe

The ISR Performance Long Tube Headers for the LS1 Swap Hyundai Genesis Coupe are purpose-built for one of the more popular V8 swaps in the drift world. Fitting a GM LS1 into the Genesis Coupe chassis means the stock truck or F-body manifolds rarely clear the frame rails, steering and chassis, and generic long tubes are never designed around this engine bay. These headers are built specifically for the LS1 in the Genesis Coupe.

Why long tubes for a swap

• Long primaries give the LS1 the exhaust scavenging that short manifolds cannot, which pays off in midrange and top end torque
• Designed around the Genesis Coupe chassis so the collectors land where an exhaust can be routed
• Avoids the trial-and-error of modifying headers meant for another car

Part of a complete swap

ISR Performance makes a range of LS swap components for the Genesis Coupe, and these headers are the exhaust side of that package. Pair them with the rest of the ISR swap parts for a setup where the pieces were designed to work together.

Fitment

Hyundai Genesis Coupe with an LS1 engine swap. Every swap is a little different, so verify your engine mount position and steering shaft routing against the header primaries during mock-up before final installation.

All ISR Performance products are designed for off-road use only.
