Built from 304 stainless steel and designed specifically to pair with the ISR VQ Swap Mount Kit. The \"HGC\" (High Ground Clearance) designation refers to the routing, which is engineered to maximize underbody clearance.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eVQ-swapped S-chassis builds traditionally require either custom-fabricated headers or generic universal headers that compromise on ground clearance and fitment. These purpose-built HGC headers solve that problem out of the box. They bolt to the VQ35DE on each side and route the exhaust path to maximize clearance under the lowered S13\/S14 chassis, then exit to a 2-bolt flange that mates to the ISR LS Swap Y-Pipe.\u003c\/p\u003e\n\n\u003ch3\u003eCritical Fitment Requirements\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eISR Performance VQ Swap Mounts (IS-240-VQMKT) required.\u003c\/strong\u003e The HGC headers were engineered around the engine position set by the ISR VQ mount kit.

The Y-pipe then bolts to any standard 240SX catback exhaust, eliminating custom fabrication for the entire exhaust mid-section.\u003c\/p\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1989-1994 Nissan 240SX (S13) with ISR VQ swap mounts and VQ35DE engine\u003c\/li\u003e\n\u003cli\u003e1995-1998 Nissan 240SX (S14) with ISR VQ swap mounts and VQ35DE engine\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Driver side exhaust header\u003c\/li\u003e\n\u003cli\u003e1x Passenger side exhaust header\u003c\/li\u003e\n\u003cli\u003e2x Header gaskets\u003c\/li\u003e\n\u003cli\u003e2x Y-pipe gaskets\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e ISR Performance\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e IS-SSHD-240VQ\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eType:\u003c\/strong\u003e VQ35DE Swap Exhaust Headers (Pair)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eVehicle Fitment:\u003c\/strong\u003e 1989-1998 Nissan 240SX (S13 and S14)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eEngine:\u003c\/strong\u003e Nissan VQ35DE (RWD configuration)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eMaterial:\u003c\/strong\u003e 304 Stainless Steel\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eRouting:\u003c\/strong\u003e HGC (High Ground Clearance)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eExit Flange:\u003c\/strong\u003e 2-bolt, mates to ISR LS Swap Y-Pipe (IS-240LS-Y)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eRequired Companion Part:\u003c\/strong\u003e ISR VQ Swap Mount Kit (IS-240-VQMKT)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eRecommended Companion Part:\u003c\/strong\u003e ISR S-Chassis LS Swap Y-Pipe (IS-240LS-Y)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eInstallation Note:\u003c\/strong\u003e Floorboard clearancing required around 2-bolt flange\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eSold:\u003c\/strong\u003e Pair (driver and passenger)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eLegality:\u003c\/strong\u003e Off-road and competition use only\u003c\/p\u003e","brand":"ISR Performance","offers":[{"title":"Default Title","offer_id":45957128782021,"sku":"IS-SSHD-240VQ","price":693.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/2718\/9701\/files\/ISRvq__89631.1562959871.1280.1280__10383.1630073074.500.659.jpg?v=1773346504","url":"https:\/\/www.isrcompetition.com\/products\/isr-performance-hgc-vq35de-swap-headers-nissan-240sx-89-98","provider":"ISR Competition","version":"1.0","type":"link"}
