Hello,i am new here and have a dilema as i am going to have my exhaust done on thursday and can't decide between these two.
Now let me start of by saying i have a 2007 Chevy Silverado Extended cab (classic) 4X4 Z71 5.3 litre 310 horsepower.
My dilema is i want a nice droney sound but am worried i will be blasted out of the cab,the shop that is doing this is going to run duals to the back
with 3 1/2 inch tips.
I would like to hear some resanance in the cab but don't want to have to blow the stereo loud to cover it???
I have also heard that the super 40 delivers better dyno results than the delta flow series .
Any help opinions !!!!PLease

Flowmaster super 40s and 44s are the way to go. The big block 50 is also a good choice if you dont want it uber loud when you get down on it.

So will the super 40 blow me out,The tech say's he's never seen anyone having one on a pickup.
He say's mainly on old muscle cars....
And also what about the 50 series suv performance??

I have a super 40 on my silverado, it sounds awesome!!
