If you want the dual look with a little more power anda healthy low rumble go with a single in dual out muffler, they work great and sound good

 

I dunno, i was gonna dual later this month...put another flowmaster on. I've got one flowmaster on my 4.3L V6..**** sounds good. Im dualing for sound, I have the government chip, cant do 100 so i'm not really looking at the performance things all that much..I jus want it loud, and want it to accelerate quicker..i street race everytime i get in my blazer and i havent met anyone willing to do 90 or better so everything before 100 i want to be spot on. but..hey.. the one flow is a nice performance sound and seems to have it's days to me lol..but turns heads more often then not. but if you're anything like me, the dual exhaust is a risk im willing to take lol.
