The ISR High Flow Cat replaces it with a less-restrictive 300 cell metallic substrate that improves exhaust flow on KA24DE, KA24DE-T, or SR20DET-swapped 240SX builds while still meeting the emissions intent of the factory cat. The result is improved exhaust scavenging, a noticeable bump in power, and a deeper, more aggressive tone, all without removing the cat entirely.\u003c\/p\u003e\n\n\u003ch3\u003eConstruction\u003c\/h3\u003e\n\u003cp\u003e300 cell spun metallic substrate. The metallic substrate is more durable than ceramic alternatives and handles the higher exhaust gas temperatures common on turbocharged builds (SR20DET, KA24DE-T) without breaking down.\u003c\/p\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1989-1994 Nissan 240SX (S13)\u003c\/li\u003e\n\u003cli\u003e1995-1998 Nissan 240SX (S14)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eBolts up to the factory exhaust or to aftermarket exhausts built to OEM specs.
