Here, take a look at these. I have the original and you can listen to them on real trucks if you click on the demo page in upper right corner.

Flowmaster 10s are the deepest, followed by original 40s

 

X2. flowmaster 10's ftw

 

i went to from a flowmaster 40 to a flowmaster 10 and neither one of them are all that loud at wide open throttle.

 

I have to kinda agree, at a solid...2000-2200 rpm its got a nice roar to it, but if you cut her wide open it kinda....just i dunno...fizzles out almost. Thats why i'm cuttin mine off and going with true dual straights after the cats

 

U have a 4.5

 

4.5 ??

 

oh sorry.. typo, i meant 4.6

 

It happens
