ISR Performance Series II EP Dual Blast Pipe Exhaust System - Resonated- Nissan 240sx 95-98 (S14)

The ISR Performance Series II EP Dual Resonated Catback for the S14 240SX delivers the aggressive dual blast-pipe look without going full volume. 3" piping through the mid and most of the rear, splitting to a staggered dual 3" tip section, with an inline resonator on the mid to keep highway cruising livable.

What It Does

Complete catback replacement for the S14. Series II construction routes the piping for more ground clearance than older ISR EP Dual catbacks, and the extended dual tips clear factory and aero bumpers cleanly. The resonator tames cruise drone while still letting the dual tips deliver the EP Dual sound under throttle. The modular architecture means you can later swap the EP Dual rear for a GT Single or EP Single rear without buying a new mid section.

Fitment

Designed for the Nissan 240SX 1995-1998 (S14 chassis). Not backward-compatible with the original (non-Series II) ISR S14 exhausts.
