Why run mufflers if you want it loud. Just put some 4" pipe back there so it will drive everyone insane......

Flowmaster 40's are pretty loud and raspy. Many have changed them out after a bit since they are so noisy...that has to say something! You can go the Flowmaster website and hear the differences. Dynomax may have a website for your enjoyment too...LOL!

flowmaster 40's not delta flow 40's (delta=quiet)

Yes, make sure you get the original Flowmaster 40 series "American Thunder"'s. Those are the loudest mufflers...unless, of course, you get some glasspacks, heat em up and stuff a garden hose up the pipe! (Not reccomended) The problem with straight pipe is the lack of backpressure. Make the truck run and sound like crap...IMO.
