Hello, i have just recently aquired some money, and i was wondering what i could put in my 2005 4.0 v6 premium mustang to make it sound better. If you have any suggestions, please help me out. Also in the ballpark of 100-1500 dollars. thanks!

 

I always liked the MAC axleback my ex's 2006 had.

 

100-150 or $100-$1500? For $100-$150 you are limited option wise, you may be able to get a single muffler replacement that will alter the sound. Or you could get a GT take off muffler.
