The MagnaFlow 106-0742 is a BRExhaust Direct-Fit replacement exhaust kit for the 5.6L V8 in the Nissan Titan, Nissan Armada, and Infiniti QX56. It is built as a multi-piece, bolt-on system, so the installer swaps in pre-formed pipe and muffler sections instead of cutting and welding tubing. The manufacturer says the box includes the gaskets and clamps needed for the job. Owners on user forums often report dealer quotes in the several-hundred-dollar range for replacing a rusted muffler and tailpipe, so a direct-fit kit at this price can make sense when the stock system is failing. Check fitment by submodel before ordering, because the years and trims listed for this kit vary across sources.
Owners on user forums frequently compare stainless and aluminized exhaust, with many recommending stainless for longevity, so review the kit's construction details with the manufacturer before buying if corrosion resistance is a priority. Drone is the other common complaint on these trucks. Forum members report that the Titan and Armada sound differently with the same exhaust, and some add an inline resonator to tame highway droning. Searches for a 2007-2010 QX56 direct-fit exhaust, a bolt-on 5.6L V8 Titan replacement kit, or a no-weld Armada exhaust install tend to surface this kit's application notes. Keep the existing emissions equipment in mind when planning the job.
No. The manufacturer states that no bending or welding is required, because the kit is designed as a bolt-on assembly.
Fitment lists for this kit differ across sources. The QX56 coverage in particular appears narrower than the 04-15 range in the product title. Use the manufacturer's vehicle fitment lookup or contact the manufacturer with your VIN before ordering.
Owners on user forums report that drone varies by model and by exhaust design, and that the Titan and Armada can sound different with the same system. Many owners who experience drone add an inline resonator to the tailpipe. This is a forum-reported experience, not a manufacturer guarantee.
The manufacturer describes this kit as a bolt-on system that needs no bending or welding, and it ships with the gaskets and clamps needed for installation. Work on a level surface with the vehicle safely supported, and dry-fit each section before tightening anything so the pipes clear the rear axle and body mounts. Factory fasteners on these trucks are often rusted, so penetrating oil and a plan for seized bolts are worth having on hand. If the exhaust leak is at the manifolds rather than the tailpipe or muffler, this kit will not correct it, and owners on user forums report that factory manifolds on these trucks can crack. I could not locate a published install sheet with torque values or a tool list, so confirm those details with the manufacturer before starting.
