ISR Performance LS Swap Header - Nissan 240sx 89-98 - 1 3/4"

The ISR Performance LS swap headers for the 1989 to 1998 Nissan 240SX are 1 3/4 inch long tube headers built from 304 stainless steel for LS1 swapped S13 and S14 chassis. They are designed to pair with ISR's own LS1 swap mounts, so the engine sits where the headers expect it to and installation into the S chassis is as simple as an LS swap gets.

Built for horsepower

With 1 3/4 inch primaries, these long tube headers provide excellent flow for higher horsepower LS applications. Long tube designs give the exhaust pulses room to scavenge, which helps the engine breathe through the midrange and top end compared to shorty or cast manifolds.

Fabrication friendly

ISR includes V-band clamps and a pair of V-band to 3 inch weld on ends. That means you can fabricate your own Y-pipe or H-pipe, or tie the headers into an existing exhaust, without hunting for matching flanges. The V-band joint also makes the collectors easy to disconnect later for service.

What's in the box

• 1x driver side exhaust header
• 1x passenger side exhaust header
• 2x header exhaust gaskets
• 2x V-band clamps
• 2x V-band to 3 inch exhaust piping ends for building your own Y-pipe, H-pipe or similar

Fitment

Nissan 240SX S13 and S14, 1989 to 1998, with an LS1 swap using ISR Performance LS1 swap mounts. Engine placement with other mount kits may differ, so check clearance before committing.

Material

304 stainless steel throughout. It resists corrosion and holds up to the heat cycling of a swapped V8 far better than mild steel.

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