ISR Performance LS Swap Y-Pipe - Nissan 240sx S13/S14

The ISR Performance S chassis LS swap Y-pipe closes the gap between swap headers and a cat back exhaust on a Nissan 240SX S13 or S14 without any fabrication. Once the ISR LS swap kit and HGC LS swap headers are in the car, this Y-pipe bolts to the 2 bolt flanges at the rear of the headers and its outlet bolts to the front flange of an existing cat back.

What it does

• Merges both header outlets into a single pipe
• 2 bolt flanges at the header ends and a cat back flange at the rear
• Eliminates custom pipe work in the one area most swaps still require it

Fitment

Nissan 240SX S13 and S14 with an LSx engine swap. Requires the ISR Performance LS mount kit and the HGC LS S chassis swap headers for proper fitment; the Y-pipe is dimensioned around that engine position and header layout.

This same Y-pipe also works with the ISR Performance VQ35DE swap kit and VQ35DE swap headers, so VQ swapped S chassis owners can use it too.

In the box

• 1x LS S chassis swap Y-pipe
• 3x 2 bolt gaskets

Install note

Bolt the Y-pipe to the headers first, then connect the cat back and hang the system before final tightening so nothing is under tension.
