Im getting a new muffler this weekend, what do you think sounds better on the 3400 flowmaster, or magnaflow?

 

don't get a slowmaster.. i'd say no muffler myself but of the two, i would take the magnaslow

 

also heard about dynomax, they sound decent im just lookin for a muffler with some good grumble to it

 

i had dynomax's and had them chopped off. hte kit that was under my car was the dynomax catback from pfyc, although it is also available from summit i believe. i hated how quiet that car was. the fateful day that they came off was this one day i reved up at a friend of mine whos parents just bought him a 2006 mustang, and he didnt even hear me. they got chopped off and i kept the glasspack that replaces the resonator. i hear they have louder mufflers, but i dont know. now, most of my tone came from the glasspack when i had taht system as wehn i chopped the mufflers off i had almost hte same tone but MUCH louder. if you want a quiet car with a small growl, go for Dynomax.
