i can say youtube doesnt give the best sounds for exhaust cuz people record them on cheap cameras with crappy microphones. Now you can get somewhat of a general idea on what it sounds like but not 100% but best bet would be to go to the mufflershop and she if they can slip different mufflers on. i just went to the shop and said i want dual outlet and they gave me some generic muffler that sounds AWESOME compared to any others ive heard (on a v6)

 

is it a 3.4 or a 5.7?

 

my 94 v6 has the nock off flowmaster duel exhaust an it sounds great but it all u its what u like
