No mufflers, no resonator, just 3\" piping splitting straight to dual 4\" tips. Built for track use where volume isn't a concern and weight reduction matters.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003ePure race exhaust: no sound dampening anywhere, full straight-through flow, dual 4\" tip outlet. It's loud, it's aggressive, and it's not subtle. This is the original (pre-Series II) ISR design, predating the modular catback family.\u003c\/p\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cp\u003eDesigned for the Nissan 240SX 1989-1994 (S13 chassis). \u003cstrong\u003eThis is a pre-Series II exhaust and is not compatible with Series II modular components\u003c\/strong\u003e (mid sections, modular rears).
