flowmaster 10 series is the loudest flowmaster. but check if its legal in your state.

 

Whats the difference between flowmaster 10 series and a flowmaster super 44 series? I want to keep all the power I can and for it to be as loud as possible.

 

You should call flowmaster and see what they recomend. The hemi outflows alot of those mufflers

 

When I got ahold of them last year they suggested the 50hd and the super 44, I ended up getting the 50.I plan on switching over to an AT or magnaflow before the end of summer.I like the sound of the flowmaster, but I still feel that the 50 dosn't flow enough

 

I just got rid of my straight pipes for 3 reasons:

1. I lost about 1 MPG vs the stock exhaust.
2. I lost a lot of low end power.
3. It sounded like ****... you have a 5.7 tho, I only have a 4.7. It may sound OK for you.
