ISR Performance Series II EP Single Tip Blast Pipe Exhaust System -Resonated- Nissan 240sx 89-94 (S13)

The ISR Performance Series II EP Single Resonated Catback for the S13 240SX picks up where the EP Dual left off, delivering the same blast-pipe aesthetic in a single-exit format. 3" piping through the mid and most of the rear, expanding to a 4" pie-cut turn-down tip. Built on the Series II architecture, with a resonated mid for livable cruise behavior.

What It Does

Complete catback replacement for the S13. The pie-cut turn-down gives the S13 an aggressive blast-pipe look at half the visible tip count of the EP Dual. Series II construction routes the piping for more ground clearance than older ISR EP Dual and GT Single catbacks, and the resonator keeps highway droning in check. The modular architecture means you can later swap the EP Single rear for a GT Single or EP Dual rear without buying a new mid section.

Fitment

Designed for the Nissan 240SX 1989-1994 (S13 chassis). Not backward-compatible with the original (non-Series II) ISR S13 exhausts.
