First of, thanks guys for helping me get an idea of what I should get. I have been told, and I have read, that upgrading the muffler is one of the easiest, cheapest, most bang for your buck upgrades out there. So I have decided that doing that would probably be my first upgrade.
While searching around the forums and talking to people, I somehow got the idea that doing the Dual exhaust conversion for a V6 doesn't do much more than upgrading the single exhaust. I have also heard that doing that might actually lower the performance upgrade compared to a simple muffler upgrade. Is this true?
Also what are other benefits, aside from the aesthetic ones, would having a dual exhaust system be over a single exhaust?
If I choose to keep the single exhaust, aside from the muffler, is there anything that needs to be changed with the exhaust system? Aside from the headers?
I have read on this website 05-07 Mustang Flowmaster V6 Exhaust | FordMuscle Magazine
that the Flowmaster muffler is really good, from what I read here people like their flowmasters. Is that article accurate?
And finally, if I do choose to go with the single exhaust route which one of these would you recommend? (I am looking for that deep rumbling Mustang sound) V6 Mustang Stuff | V6 Mustang Performance Parts and Accessories
