I know alot of you guys are running Flowmaster 40 mufflers. Are they the Delta Flow or the regular 40. I 'm not to sure what the differance is and what works better on our trucks

 

I went with a Super 40, which has some Delta Flow technology in it. Here is a post I did on my muffler install, but there is a graph that kinda breaks down the differences between the different models of 40 series.

Good post, I think I am convinced. Do you need to do any other mods with the flowmaster as far as intake or anything, I dont have anything else done to mine, so I just want to make sure I dont screw anything up

 

No other mod is needed.... but it helps ... do what your budget allows you to do... You can listen to my flowmaster 40 series delta in my signature.
