hey man....i have that same set-up and the sound is killer. it has a more raw and powerful sound than a flowmaster..but it still has that chambered muffler tone..you did the smart thing by getting the h-pipe too b/c when i got mine i got an x-pipe and it is really raspy..it sounds ok on the outside but opn the inside it sounds likeit has a nasty exhaust leak. the h-pipe has a more deep powerful tone. congrats on the purchase.
