I spoke with one of Magnaflow's headquarter technicians, Ron, who described the failure to me. The inside portion of pipe within the muffler literally broke off inside of the casing, causing a condition known as a "floating core." The muffler sounded worse than a fart can. Every bump, the improperly welded pipe moved past the outlet of the muffler and let out a loud burp. After about 3 phone calls to Magnaflow, Amazon.com sent a new replacement.
One of our other vehicles, a 1992 Toyota Pickup, has been running a Magnaflow 18" oval muffler for about 8 or so years. This led me to believe that the specific muffler I had on my 4Runner was just a fluke. I returned to Collin's Muffler and Hitch and paid $75 to switch out the mufflers.
Inside of the first muffler, it was clear that the material inside had burnt away (as per usual), while the actual metal pipe separated from the inside casing. This was heavily disappointing, at least Ron was correct with his diagnosis....
The new muffler was a ticking time bomb. QUOTE]
COB,
What a horrible experience! I have had lots of success with Magnaflow mufflers on my Maxima's but that's a different application. Have you considered copying this post on to the Magnaflow Facebook page or even posting the story minus the videos? I have successfully used that approach with two Fortune 500 companies and my issues were resolved within 48hrs. Call it Public Shaming or access to Corporate Customer Service, either way it works. No company wants bad press.
Does Borla make exhaust for SUV's?
Good Luck
