Heck, I didn't know that about the Flowmasters, learn something new everyday I guess, I thought it was just the mufflers with batting that got louder. My Magnaflow didn't get much louder on me, but of course once I sealed up the leaks that would make it a lot quieter. So I very well could have been quieter before and got louder. I've read that the material they use is supposed to be better about not breaking down because it's a steel wool or something like that. But the cheaper ones will use fiberglass, which I've heard the Dynomax mufflers will eventually get louder. Wish I could give you a better idea on the sound of it, but you've got a different engine than I do, so the sound and connections would be much different. If you do decide on a Magnaflow I'd check at partsplusautostore.com they had excellent prices on their mufflers and I think I got a steal on the polished stainless, most places were selling for about $100 and I found it for $60 there. Good luck, this is probably one job where I don't worry too much if I don't get it just right because at least it's easy to fix, for the most part.
