ISR Performance Series II - Resonated Mid Section Only - Nissan 240sx 89-94 (S13)

The Series II Resonated Mid Section for the S13 240SX is the modular front-half component of the ISR Series II exhaust family. Drops between the factory front pipe and any Series II S13 rear section (GT Single, EP Single, or EP Dual). The inline resonator keeps highway cruising livable while letting the rear section define the tone.

What It Does

Standalone resonated mid section. The resonator takes the edge off droning at cruise without choking flow, which is the right call for daily-driven S13s. Pairs with any Series II S13 rear, so you build the catback you want by combining this mid with your preferred rear style. If you want maximum volume and don't mind cruise drone, the non-resonated version (IS-S2NRMD-S13) is the alternative.

Fitment

Mid section only. Not a complete exhaust system. Works exclusively with ISR Performance Series II S13 rear sections. Will not work with original (non-Series II) ISR S13 exhausts, OEM exhaust, or any other manufacturer's catback. Designed for the Nissan 240SX 1989-1994 (S13 chassis).
