Right now I have a 2-chamber flowmaster turned down before the axle with the stock Y-pipe. I want something that is real deep at idle but not extremely loud when driving. I really like the turn down because it screams at WOT. Any opinions would be great! thanks

 

the 1 chamber flowmaster if you still hae your cats on will be a little louder on start up and cruising but on the highway it is very quiet.

 

A flowmaster quiet on the highway?? Well, just watch out for the drone.

 

my flowmaster is very quiet on the highway. but i think it is a 3 chamber or something. my truck sounds more like a mustang than a truck. it does get louder when you punch it. but not insanely loud.

 

actually the reason the 2 chambers are so bad on drone is becasue of the v chambers in the muffler. it hitting a wall and goign around. the 1 chamber which I started with on my truck, jsut has one of these instead of a couple of them. it sounded deep at start up not to loud and on the highway you could barely hear it, vry little drone unless your in the city then their is a little. I think it sounded better then my buddies 2 chamber dumped. IMO
