What year Ram?

The magnaflow single in/out system on my 2005 Ram 1500 has objectionable drone at 2000 rpm. Sounds great around town, but I want earplugs when cruising at 70mph or towing a trailer. I wouldn't personally buy one again.

The Corsa systems are advertised as having no drone. I don't know how true it is but I haven't met anybody who complained about them.
