So i am the the web page: http://www.v6mustangstuff.com/Exhaust.html It allows you to buy flowermaster 2 and 3 chamber mufflers. What is the difference? Also...if i just buy one or the other and install it myself would it give me a better grumble sound? I dont care about horsepower or anything there...or even the duel exhaust looks. I also dont want it to be louder....just a more throaty sound. Will one or the other do it for me? Thanks guys.
