ISR Performance High Flow Cat Nissan 240SX 1989-1998 S13 S14 | IS-HFC-240

Part #: IS - HFC - 240. ISR Performance high flow catalytic converters are custom - crafted with a high - flow 300 - cell spun metallic substrate. They're less restrictive than the stock ones, helping you boost power while converting harmful exhaust gases. These HFCs can be bolted onto factory or aftermarket exhausts (as long as the aftermarket exhaust follows OEM specs). They also give your exhaust a more aggressive tone. For off - road use only.

How to use: First, make sure your vehicle is a Nissan 240SX S13 or S14 from 1989 to 1998. Then, unbolt your old catalytic converter and replace it with the ISR Performance high flow cat. Ensure it's securely attached to your exhaust system, whether it's a factory or an aftermarket exhaust that meets OEM specs. Note: This product is for off - road use only. Do not use it on public roads. Maintenance: Periodically check the bolts to make sure they're tight. If you notice any unusual noises or performance issues, have it inspected by a professional.
