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

The ISR Performance Series II EP Dual Non-Resonated Catback for the S14 240SX is the loudest, most aggressive S14 catback in our lineup. 3" piping through the mid and most of the rear, then splitting to a staggered dual 3" tip section. No resonator, so what you hear is unfiltered EP Dual blast-pipe character.

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. Without the resonator, expect more volume and cruise drone than the IS-S2EPDR-S14 Resonated counterpart, with a more aggressive note that matches the visual aggression of the dual blast tips. 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.
