I want to buy a new O/R pipe for my car. It currently has stock exhaust except for flowmaster mufflers. I believe the mufflers are 50 series because they aren't much louder than stock but they are nice and deep. Should I get an o/r x-pipe or o/r h-pipe. I've heard the an h-pipe is more torque and better sound and x-pipe is more hp and more raspy sound. My question is the power difference between the h-pipe and x-pipe noticable? Which pipe should I get O/R h-pipe or O/R x-pipe?
