my junk has so many rattles- roars -knocks -creaks and squeaks i would never hear a bad muffler..

 

1. You have to have your reciept or invoice from where you bought the mufflers. That invoice will have the part number that they need. I couldn't find mine either, but a call to the company I bought them from did the trick.
2. No they ship first and have you reuse the same packaging to return them.
3. That's what I did. My local muffler shop took a look at it, I was hoping it wasn't a cat. They were able to figure out it was a bad weld. But they couldn't give an exchange. It has to come from the corporate office.

 

Flowmaster is great to deal with on these swaps. Even a year later I'd be surprised if they didn't swap it for you.

 

Hmm, need to check as I have a new buzzing noise???

As for the wife... Mine "borrowed my car" and when she brought it home I had a set of 4:10's.... Gotta love her for that.

 

Ok I talked to FLowmaster and Basically your SOL if you don't have that receipt. However I have a local muffler shop that is a flow dealer and they are going to see if they can do somthing for me. I hope they can. I hate the buzzing noise!

 

Look for my post with a vid of what you are describing. I made a vid today showng the O/R x pipe flowmaster and vibrant resonator set up and I noticed it when I watched the vid. LOOK FOR MY POST
