I just had the flowmaster 50 suv muffler installed on my 09 jk 4 door. And I think I am having regrets about it. To me from the cab it sounds to be a bit "ricey" for lack of better word. At idle is sounds ok from the outside, but driving it around town it sounds a bit like a suped up honda. Is there any way besides changing out the 50 that I will be able to make it sound a little more deeper and throatier and less like I should mount a huge spoiler on the back of it? Will adding a Cold Air intake help this out? I have read a few other threads on here about people that are happy with the flowmaster 50 sound and thought it did sound deep. Could it just be my install?

 

can you add a second muffler to work as a resonator?
