just wondering if anyones running the new muffler dynomax has out, just saw in a magazine they are offering a 90 day return policy, so if your not happy with it, supposedly you send it back for a refund. i'd have to say seeing that shows some serious confidence in their muffler

 

I had this muffler put on my 08 hemi sport 4x4, it sounded alright. It did what was advertised as far as drone. The problem I encountered was after about a month of use it developed a ticking noise which was incredibaly annoying, It was coming from that valve tapping on the metel when closing, So I removed the muffler sent it back and got a refund. I purchased a Hooker aero turbine and couldnt of been more happy. Deep tone not to loud and most importantly no drone. I hope this helps you out
