The MPI Automotive SSMBM799MF is a set of 3in rear mufflers for the Jeep Grand Cherokee SRT and SRT-8 6.4L Hemi V8 (2012–2020), also listed for the Grand Cherokee 5.7L V8 (2011–2015). As the rear-muffler section it's where the system's final volume is set, not the centre or the cat.
What does a rear muffler do on the SRT?
The rear mufflers are the last quietening stage before the tailpipe. A chambered, absorptive muffler softens overall volume and rounds off the harshness, so on a 6.4L Hemi SRT it sets how loud the car finishes at the back. Built in 3in to suit the engine's output, the SSMBM799MF replaces the factory rears as a matched set. This is the rear section specifically — it works with whatever centre and cat hardware the car already runs, so it's the targeted change for owners who want to alter the final note without touching the rest.
Which Grand Cherokees is it listed for?
It's listed to fit two applications: the Grand Cherokee SRT and SRT-8 with the 6.4L Hemi V8 from 2012 to 2020, and the Grand Cherokee 5.7L V8 from 2011 to 2015. That covers both the hot SRT models and the earlier 5.7 over their respective year ranges. Because it spans several model years and two engines, confirm your exact variant and year with the workshop before ordering so the rear hangers and outlets line up.
Is it road legal?
This is a rear-muffler section. It doesn't include or delete the catalytic converter, so the cat-delete off-road rules don't apply to this part. A rear-muffler change does alter how loud the car finishes, so confirm the in-service note and any state requirements with the workshop before fitting.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits Grand Cherokee rear-muffler sets in-house across the Illawarra, hanging the rears, checking the tailpipe alignment and confirming the section suits your year and engine. The SSMBM799MF carries a published RRP of $1,350.91; send your build and we'll confirm fitment and book the bay.
