Jeep Grand Cherokee SRT8 6.4L, 1 7/8in Extractors, With 3in outlets.
Category: Extractors and headers


The MPI Automotive FX-797 is a set of 1-7/8in primary extractors with 3in outlets, listed to fit the Jeep Grand Cherokee SRT8 with the 6.4L engine. It replaces the factory exhaust manifolds at the heads.
An extractor, or header, swaps the cast factory manifold for tuned-length tubes that merge downstream to reduce back-pressure off the heads. On the FX-797 the primary tubes are 1-7/8in and the collectors step out to 3in outlets, which sizes the header to a large V8 like the SRT8's 6.4. It's a set per bank at the very front of the exhaust. We can't publish power or sound figures, because the supplier doesn't.
The FX-797 is listed to fit the SRT8 6.4L Grand Cherokee. The supplier hasn't published exact build years, so confirm your specific engine and build with the workshop before ordering. We treat it as 'listed to fit' rather than guaranteed, since feed data can be imperfect.
Oak Flats Muffler Men fits V8 extractors in-house. On a 6.4 SRT8 we check head-face condition on both banks, stud access and how the 3in outlets mate to your existing system. Send your Grand Cherokee's details and we'll confirm the FX-797 and book the bay.
The FX-797 is an MPI Automotive part with a recommended retail of $1,650.26. As a large V8 header set it may be ordered in rather than stocked, so ask us about lead time when you book.
