hey my name is jon i got an 02 dodge ram 1500 3.7l v6 and over the weekend i had a dual flowmaster 40 series put on at a local place and i couldnt believe how loud it was omg it sounded better than my friends mustang gt and my brothers 00 5.9L dodge with a cherry bomb on it i would deff say get the flowmaster its deff worth the money!!!

 

dude a single inlet dual outlet flow super 40 series sounds great so many people have told me it sounds like a v8 when it idles but when you get on it it still sounds like a v6 when i get my truck back from the body shop (gettin a roll pan) ill send you a clip

Oops did I leave a space between dodge and talk, remove it and you will find my previous sounds.

 

What does it mean when the exhaust is "dumped"?

 

You got the muffler and then right on the out pipe of the muffler, you add a turn down pipe.
Basically, "dumped" at the muffler, you dont let it run all the way out the back or to the side. Right after the muffler you turn it down as in "dumping" the exhaust down.
I mean you could have it all the way to the back, but then you turn them down, not straight out.

 

So I guess that makes it louder???

 

The "theory" is that the sound would bounce from the ground, up to the bed cavity and yes make the sound louder.
