I had a 70 series on a Vortec 5.7 and loved it, not loud, no droan, you get on it had a rumble. Flowmaster has some sounds on their site.

I had dual 50 series on my 03, and was much louder than I had expected. However I liked it, it was not an annoying loud just deep and throaty.

I had a 70 series on my 04 2500 with a 6.0 and I asked the Flowmaster rep about the drone on my truck with the 70 series muffler and he said that I needed to add a resonater to the left exhaust pipe after the cat to eliminate the drone. I never did the resonator so I don't know if that would do the trick.

Then I tried a FloPro on my truck (due to reccommendations on this an danother site) and it was quieter than stock. It was the Big Oval direct replacement. I yanked that thing of and put in a Corsa. Up to that point, all the money I had spent on my exhaust system was a waste. The Corsa sounds great and it's a quality setup. The Corsas are pricey, but keep checking ebay, they're on there every now and then.

Got Ya I Know The Old One I Got Works Awesome. No Drone At All. I Do Wish It Was A Little Louder,but The Wife Likes It At Least.
