hi, i have a 2002 v6, and recently had 2 40 series flowmaster mufflers put on with turn downs. i am wondering what sound, or performance change there would be to get a x, or h pipe instead of the y pipe i have on now. i do not know much about any of these pipes so any explaining would help a ton. also, with the turndown pipes, i have a very deep sound but kinda want to put pipes out back. what would the change in sound be then? i am looking for a louder tone outside the car then i have now. is there anything else that would help make my car louder? thanks for any help.
