I did the mufflex 24 and at first I was disappointed....it seemed like it was no louder than stock.....but after about 200 or so miles it woke up. At idle it isn't very loud but when u get going u know it isn't stock...

Ps...a week earlier I did a k&n intake and the cowling sound was really loud under the hood....after about a week with the combo of the magnaflow and k&n the sound has all moved to the rear! I could see how a 18" would drone...the 24 is just enough.

 

What do you guys think about the sound when your ram is only running on 4 cylinders?

 

With the 24", it's ok. Sounds a little off but under low throttle it still has a nice sound to it.

 

I agree...not a huge change when the mds kicks in...I feel it more than I hear it.
