Oh yeah they're louder. It's a straight through muffler with stainless steal packing so it flows more and is louder at WOT.

Jegs has a $25 rebate right now per muffler. That's a smokin' deal.

Not nearly as much but some. But, my cab is all metal on the inside so probably any muffler would drone some. Not bad cruising. If you have a wood bed install the mufflers underneath it. Wood helps absorb the sound.

could u tell a diffrence in response with the dynomax mufflers vs the flowmasters

I did notice a slight power increase. They flow more than the flowmasters did. So much more that I actually lost 2" of vacuum. They sounded great at first but now that the packing is starting to blow out they're REALLY loud. I like em' but I may go back to a chambered muffler.
