Built for track use where weight reduction and sound aggression matter more than refinement.\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 3\" tip outlet. It's loud, it's aggressive, and it's not subtle. The dual-tip rear gives the S13 the blast-pipe look without going as wide as a 4\" tip variant. 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). If you want a system you can later modularize with different rear styles, see the Series II catback lineup instead. The IS-EPDual-S13BO is the dual 4\" tip variant in the same pre-Series II family.\u003c\/p\u003e\n\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e ISR Performance\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e IS-EPDual-S13\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eType:\u003c\/strong\u003e Straight-pipe catback exhaust (race)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eVehicle Fitment:\u003c\/strong\u003e Nissan 240SX 1989-1994 (S13)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003ePiping:\u003c\/strong\u003e 3\" straight, splitting to dual 3\" tips\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eMufflers:\u003c\/strong\u003e None\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eResonator:\u003c\/strong\u003e None\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eSeries:\u003c\/strong\u003e Pre-Series II (legacy ISR design, not modular)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003e4\" Tip Variant:\u003c\/strong\u003e IS-EPDual-S13BO (same pre-Series II family, dual 4\" tips)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eSeries II Alternatives:\u003c\/strong\u003e IS-S2EPSR-S13, IS-S2EPSNR-S13 (EP Single), IS-S2GTR-S13\/IS-S2GTNR-S13 (GT Single), Series II EP Dual catbacks (S13)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eSold:\u003c\/strong\u003e Complete kit\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eLegality:\u003c\/strong\u003e Off-road and competition use only\u003c\/p\u003e","brand":"ISR Performance","offers":[{"title":"Default Title","offer_id":45957111677125,"sku":"IS-EPDual-S13","price":440.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/2718\/9701\/files\/P1170114__93846.1630073044.500.659.jpg?v=1773346764","url":"https:\/\/www.isrcompetition.com\/products\/isr-performance-straight-dual-3-tip-exhaust-nissan-240sx-89-94","provider":"ISR Competition","version":"1.0","type":"link"}
