Hey guys im about to put on some flowmaster 2 chambers on my 5.0. Replacing the stock mufflers and stock h pipe. The car is all stock. Besides changing sound, will there be any changes in horsepower? What kind of gains can I expect with this combo compared to stock exhaust. The rest of the car is stock as well. Also will just the flowmasters with the stock h pipe add any power? (might be a while before i get the x pipe)

Thanks for any replies.

I have that set up and like it. I just wish I would have gotten an h instead of the x. The h gives it a deeper tone. Either sound great though.

Do the H and enjoy the sound! Best sound you can get from a 5.0, IMHO.
