Im thinking about getting either a off road H pipe or a set of headers. Which one would help my car breath the best? How would each one help or hurt my car?
What kind of car do you have? Do you already have some mods? Headers on a stock motor will not do as much good as an o/r h-pipe. Got with the h-pipe, it made mine sound wicked! and it freed up quite a bit of HP. Plus, I didn't experience any loss of low-end torque like some people say. You can get a MAC o/r h-pipe for $129 through 50resto.
