I put the Magnaflow cat-back on my Magnum about 4 monthes ago and was very dissappointed with the sound. The car did not sound any better than the stock system at idle, and only slightly better under hard acceleration. I finally got fed up and brought it down to my local muffer shop and had them replace the muffler with a Magnaflow 10790 crossover and stainless pipes. (no more muffler!) The new sound is perfect, a nice little rumble at idle and a GROWL at WOT. I have not had a chance to take it out on the highway yet, I will report back later.
