Hello all, sorry for the long post, just wanted to share an experience with current Pilot owners about Magnaflow Exhaust and their warranty procedure. For a little bit of background, I own 2005 Infiniti G35 coupe which needed to have the oem cat back exhaust system replaced due to rust several years ago. I did some research online and settled on Magnaflow exhaust because of the glowing recommendations from users and their price point compared to other exhaust manufacturers. I ordered a cat back system from a authorized online distributor for approximately $1,000 and had it delivered to my home and had it installed by a local mechanic. Several years after the Infiniti had the Magnaflow exhaust mounted, the OEM catalytic converter on my 2004 Honda Pilot had broken at the flange and needed to be replaced in 2017. I was happy with the Magnaflow exhaust and the workmanship so I didn't hesitate to go online and order a Magnaflow catalytic converter for the Pilot. The Pilot required the pricier California cat converter because I'm a NY state resident and NY requires it to pass emissions. I ordered the Magnaflow cat converter from an authorized online distributor, had it delivered to my home and installed by a local mechanic. Fast forward to March of 2020 and the Magnaflow cat converter failed with the internals breaking apart and clogged the exhaust causing it to bog down due to the exhaust restriction. The Pilot had to be towed to my local mechanic where he diagnosed the cat converter failure to be the problem and wanted to know how to proceed. I told him that it was a fairly new cat converter (3 years old at this point) and that I would contact Magnaflow to start a warranty claim for a replacement. I called Magnaflow customer service on 3/10/2020 and told them that their cat converter had failed and wanted to know the steps to file a warranty claim. The Magnaflow representative asked the usual questions and wanted to know where I purchased the cat converter. I told the Magnaflow representative that I purchased it form an authorized distributor and at that point he wanted a copy of the receipt. I had searched for the receipt prior to calling Magnaflow customer service but could only find the receipt from my local mechanic which listed the work performed to install the cat converter. I advised the Magnaflow representative of this fact. He advised me to contact my credit card company and try to track the purchase this way. I have approximately 10 credit cards and tried to research the ones that I use on a daily basis for purchases. I also had closed the accounts of some credit cards that I no longer used. My mechanic at this point wanted to know what to do with the vehicle because it had been sitting in his shop for about a week while I was trying to research where I purchased the Magnaflow cat converter. I told him to proceed to change the cat converter with an aftermarket converter because of the problems tracking the original Magnaflow receipt. I have the defective Magnaflow cat converter with the serial numbers and model number clearly visible and ready for Magnaflow if they decide to warranty their product with a visual inspection. Please, take this a warning from someone who is getting the run around from Magnaflow....if you purchased one of their products in the past, find the receipt and keep it handy!!
