Xforce Exhaust.4L Header & High Flow Ca for selected vehicle applications.
Category: Extractors and headers


The XForce HS-JC12-KIT is a header and high-flow cat kit listed to fit the Jeep Grand Cherokee SRT8 with the 6.4L engine. It pairs tubular headers with high-flow catalytic converters as a matched front-of-system package.
A header and cat kit replaces the cast factory manifolds with tubular headers and supplies the catalytic converters that go behind them, so the front of the exhaust is renewed as one matched set. The cats here are listed as high-flow, meaning they're designed to pass gas more freely than a standard cat while still housing a catalyst. On the SRT8's 6.4L this is where the exhaust first gathers. Because the kit includes cats, it keeps catalytic converters in the system rather than deleting them. We publish no flow, power or sound figures and won't quote any.
It's listed to fit the Jeep Grand Cherokee SRT8 with the 6.4L engine. The variant and engine both decide the fit, so confirm your exact SRT8 build with us. We check the listing against your vehicle before ordering rather than assuming the feed is exact.
This kit supplies high-flow catalytic converters rather than deleting them, so it isn't a cat-delete pipe. Whether the finished setup meets NSW registration requirements still depends on the cat specification, the rest of the system and how it's signed off, which we'll go through with you. No compliance approval is published by the supplier and we won't imply one.
