ISR Performance HGC LS Swap Header - Nissan 350Z 03-08 - 1 3/4"

ISR Performance High Ground Clearance LSx 350z swap headers are built out of high quality 304 Stainless Steel and designed to pair with our own LS Swap mounts to allow for a simple and easy installation into your 350Z with maximum ground clearance in mind. Constructed with 1 3/4 piping, the ISR Performance headers will provide excellent flow for higher horsepower applications. 

These headers were designed to pair with our own LS Swap mounts (IS-350-LSMKT) and to fit your existing 350Z Y pipe allowing a quick and easy install to your current exhaust or upgrading to an ISR Y pipe and cat back exhaust.

If your 350z has a production date of 07/06 - 11/06 you may need to modify the factory steering rack hardlines for header clearance. Please check your production date and steering rack to clarify.  If you are utilizing an LS3 engine with OEM knock sensors in the OEM placement you will need to relocate the knock sensor to an alternate mounting boss for proper clearance from the primaries.
