Just writing to say my recent experience with Dynomax (Tenneco, Inc.) and their customer service. Long story short i started gettin' a rattling noise in the muffler. I immediately thought great probably a busted baffle or something. I really did not want to spend for a new muffler plus install. Took it to the shop i got it from cause i thought i had a lifetime warranty. They look at me and are like no man nothing like that on this....
SO i was kinda pissed cause this is what i was told a year ago when i had it put on. Went to Dynomax's website and looked up warranty information. Sure enough lifetime warranty on original install and owner. Hey that's me!
Called up the customer service and explained the situation to customer service. She transfers me to tech support to talk with them to see what they think is the cause of this rattling. He also suspects its a baffle inside that is possibly broken somehow.
Get transferred back to the girl in cs, told her what tech support said. She immediately set up a order for a brand new muffler UPS to my house. No charge of course.
I was very happy and all she wanted was an original receipt faxed and she said that i should be getting it next week.
Just wanted to share a experience with this company and how their policy and service pulled though for me.
