wasn't really sure how they would sound with a 3.8L but I guess it is what it is its not some monster v8.But yes I Really do enjoy the deep sound, Ive ALWAYS loved the sound of FLOWMASTER.

WARNING: for those of you who want their tiny 2.4L engine to sound like a deep harley (myself included), you are going to need more than the muffler itself. I took out the intake resonator a couple days before I got the muffler and was impressed by the change of sound. It wasn't much but it was cool for the time being. I got the muffler in a very small amount of time and put it right on. It wasn't much louder than stock... So I cut out the exhaust resonator and wow... what a difference in sound.
