The MagnaFlow BRE kit, sold under MagnaFlow's BRExhaust direct-fit line as part 106-0012, is a replacement exhaust for the 2002-2007 Jeep Liberty KJ. It is positioned as a reliable, high-quality alternative to the OEM exhaust, and MagnaFlow lists it on its own 2006 Liberty replacement exhaust page. The main trade-off is material: the manufacturer specifies aluminized steel construction with a 2 year warranty, which costs less than stainless but needs a rust check before you buy. For a buyer replacing a corroded factory system, a fresh direct-fit kit with its own hardware and warranty is a more predictable route than salvaging rusted parts. Searches for 2002-2007 Liberty KJ direct-fit exhaust, 106-0012 replacement, and BRExhaust aluminized cat-back tend to match this listing.
Installation is a bolt-on job, but rust and seized fasteners drive the effort. One owner on a user forum said an impact wrench was a godsend for the old exhaust bolts. Another owner who swapped a cat-back on a lifted KJ reported doing the whole swap without jacking the Jeep up, and advised to recheck the clamps after about 50 miles and look for exhaust leaks. Owners also describe the job as quick on this platform; one user said a Magnaflow cat-back took about 20 minutes to install including taking the old exhaust off, though that report is for a different Magnaflow model and your time will depend on corrosion.
Yes. The manufacturer lists a spring bolt kit as included with this direct-fit system.
The manufacturer states the BRExhaust direct-fit kit is covered by a 2 year warranty.
Owners on user forums who have swapped a Magnaflow cat-back on a Jeep KJ have reported roughly 20 minutes including removal of the old system. Rusted fasteners and lift height can add significant time, so plan for more on an older vehicle.
Plan on a driveway or lift setup and an impact driver for corroded hangers and clamps, since owners on user forums consistently point to old bolts as the slowest part of the job. A user on a 4-inch lifted Liberty reported finishing the swap without jacking the vehicle, so ramps or stands are helpful rather than mandatory on a lifted truck. After the first 50 miles, recheck every clamp and listen for leaks at each joint, because a loose clamp is the most common cause of a new exhaust ticking or drone. Confirm fitment against your VIN with the manufacturer before ordering.
