A good header can be pretty expensive (which is why I still don't have one

). My advice as a fellow accord owner is to grab an intake with a good (K&N) filter and if you'd like to get an exhaust go right ahead but don't expect to be anywhere near fast. You got a peppy lil engine but it takes a lot of doing to make it fast. Your money is better spent in appearance mods so that way when you get passed by the faster sedans out there you'll look good doing so
