The MagnaFlow BRE Exhaust Kit, part 106-0015, is a direct-fit replacement cat-back system from the BRExhaust line, built for the 3.5L V6 in the 2006-2011 Chevrolet Impala and 2006-2007 Monte Carlo. The manufacturer engineers its direct-fit exhaust systems to match original equipment specifications for year, make, model, and engine, requires no cutting, bending, or welding, and uses a multi-piece bolt-on design that routes around the same axles, crossbars, and brackets the factory system uses. Compared with a stock system that has corroded behind the catalytic converters, this kit gives a Monte Carlo or Impala 3.5L owner a fresh, complete system from behind the cats to the tips.
The main purchase case is durability and flow. The manufacturer says its mandrel-bent pipes promote better exhaust flow than the crush-bent pipes common in competing replacement systems. BRExhaust direct-fit kits are built from aluminized steel and carry a 2 year warranty. Owners on user forums typically describe cat-back upgrades on these V6 cars as a sound and appearance change more than a power gain, so buy this kit for a durable, OEM-style fit rather than a horsepower number. The kit replaces only the piping and muffler components downstream of the catalytic converter, which keeps the emissions hardware intact.
The manufacturer states its direct-fit kits replace only the piping and mufflers downstream of the catalytic converter, so you keep your factory converter. Listings for this specific part vary on whether a converter is included, so confirm the contents with the manufacturer before ordering.
Owners on user forums report that factory-style rubber hangers and insulators often need replacing or adding on these cars, and one owner fabricated a replacement drivers-side hanger bracket during a similar install. Inspect your existing hangers before you begin.
Because the kit is a bolt-on design, most owners can complete it in a driveway on jack stands with ordinary hand tools; owners describe needing little more than a wrench and a new catalytic converter gasket. The manufacturer says basic automotive knowledge may be needed for proper installation, and professional installation is always recommended. Plan to remove the old system from the converter rearward, check the hangers, and confirm the new pipes clear the rear end before tightening the clamps. The manufacturer also publishes an install video on a 2007 Impala, which is worth watching before you start. Confirm fitment with the manufacturer's vehicle selector before you order.
