Hello all!!Posted this in the exhaust area also just want to get feedback before thusday.
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

Welcome to the forum! Don't be shy and stay in the Silverado section now!!

Super 40 or Super 44 will give you the best. Typically glasspacks will blow you out of the cab. The "big-block 50" is a good muffler for quiet in-cab and deep-toned outside, but its not very loud.

Welcome to the forum!! For clarification, the super 40 is a delta flow muffler as well. The super 40 with tips out the back will give you a nice sound and wont be too loud inside. Where you start to run into problems with loud interior resonance, is when you dump, or turn down, the pipe under the bed right after the muffler.
